If it is required that this property continue to evaluate to null, it can be explicitly set to that value. Now, the method will succeed and return a valid string that omits the inaccessible portions of the certificate.

Any code depending on XCertificate2. ToString Boolean should be updated to expect that the returned string may exclude some certificate data such as public key, private key, and extensions in some cases in which the API would have previously thrown.

ToString Boolean. Attempts to retry connection open requests will occur almost immediately after transient connection errors.

This change allows the connection open attempt to be retried immediately for Azure SQL databases, thereby improving the performance of cloud- enabled apps.

For all other connection attempts, the connection pool blocking period continues to be enforced. This behavior is problematic for connections to Azure SQL databases, which often fail with transient errors that are typically recovered from within a few seconds.

The connection pool blocking feature means that the app cannot connect to the database for an extensive period, even though the database is available and the app needs to render within a few seconds.

If this behavior is undesirable, the connection pool blocking period can be configured by setting the System. PoolBlockingPeriod property introduced in the.

The value of the property is a member of the System. PoolBlockingPeriod property to AlwaysBlock. OpenAsync SqlConnection. Open SqlConnection.

OpenAsync CancellationToken. Also, this issue has been fixed in the. When requesting Unicode character categories in.

NET Framework versions. This change mostly affects Cherokee syllables and New Tai Lue vowels signs and tone marks. GetUnicodeCategory String, Int String representations of System.

ContentDisposition 's have been updated, beginning in 4. DateTime with two digits. This causes ToString to return a slightly different string in 4.

Note that ContentDispositions are sometimes serialized via converting them to strings, so any ToString operations, serialization, or GetHashCode calls should be reviewed.

Do not expect that string representations of ContentDispositions from different. NET Framework versions will correctly compare to one another.

Convert the strings back to ContentDispositions, if possible, before conducting a comparison. ToString ContentDisposition.

With this improvement, client certificates that are used to authenticate to a server must be configured for client authentication.

Similarly server certificates that are for the authenticating a server must be configured for server authentication.

With this change, if the root certificate is disabled, the certificate chain validation fails. The same change was also made to.

NET Framework 3. You can find more information here. This change is on by default and can be turned off by a configuration setting.

It now returns false for any verification failure. CryptographicException if the signature itself is badly formatted. Any code whose execution depends on handling the System.

CryptographicException should instead execute if validation fails and the method returns False. SignedXml and System. EncryptedXml lead to different run-time behaviors.

For example, If a document has multiple elements with the same id attribute and a signature targets one of those elements as the root of the signature, the document will now be considered invalid.

Documents using non-canonical XPath transform algorithms in references are now considered invalid. Documents using non-canonical XSLT transform algorithms in references are now consider invalid.

Any program making use of external resource detached signatures will be unable to do so. Developers might want to review the usage of XmlDsigXsltTransform and XmlDsigXsltTransform , as well as types derived from Transform since a document receiver may not be able to process it.

Transform System. DataContractJsonSerializer fails to serialize or deserialize due to missing 'known types' has been clarified.

Apps should not depend on specific exception messages. If an app depends on this message, either update it to expect the new message or preferably change it to depend only on the exception type.

Product versioning has changed from the previous releases of the. NET Framework, and particularly from the. NET Framework 4, 4. The file and product versioning for.

NET Framework files has changed from the earlier versioning scheme of 4. You can see these new values when you view the file's Properties after right-clicking on a file.

Version property returns the fixed version string 4. Note that we do not recommend application code taking any new dependency on the Environment.

Download information is found at the bottom of the page. Invariant Boolean Contract. Requires Boolean. EmailAddressAttribute , System. UrlAttribute , and System.

This helps to reduce security vulnerability such as avoiding the possibility of a Denial of Service attack using specific regular expressions.

If you find that regular expressions in your web application do not work after upgrading to. When using NetTcp with transport security and a credential type of certificate, the SSL 3 protocol is no longer a default protocol used for negotiating a secure connection.

In most cases there should be no impact to existing apps as TLS 1. All existing clients should be able to negotiate a connection using at least TLS1.

If Ssl3 is required, use one of the following configuration mechanisms to add Ssl3 to the list of negotiated protocols.

SslProtocols TcpTransportSecurity. In the Microsoft Service Trace Viewer tool , ComboBox controls were not displayed in the correct color in certain high contrast themes.

The issue was fixed in. However, due to. NET 4. If you encounter compatibility issues with this change on the. Object Cache Store. By using the new cache providers configuration section, developers can plug in new implementations of an object cache for an ASP.

Memory monitoring. The default memory monitor in ASP. NET notifies applications when they are running close to the configured private bytes limit for the process, or when the machine is low on total available physical RAM.

When these limits are near, notifications are fired. For some applications, notifications are fired too close to the configured limits to allow for useful reactions.

Developers can now write their own memory monitors to replace the default by using the ApplicationMonitors. MemoryMonitor property.

Memory Limit Reactions. By default, ASP. NET attempts to trim the object cache and periodically call GC.

Collect when the private byte process limit is near. For some applications, the frequency of calls to GC. Collect or the amount of cache that is trimmed are inefficient.

Developers can now replace or supplement the default behavior by subscribing IObserver implementations to the application's memory monitor.

Ability to configure the default message security settings to TLS 1. This is an opt-in setting; to enable it, you must add the following entry to your application configuration file:.

WCF includes a number of code changes that eliminate race conditions, thereby improving performance and the reliability of serialization options. Starting with applications that target.

Dynamic DPI changes the layout and appearance of forms and controls when the user changes the DPI or display scale factor of a running application.

This is an opt-in feature in. For the impact of this change on application compatibility, see the Application compatibility section.

For more information, see Announcing. Data annotation validators enable you to perform validation by adding one or more attributes to a class property.

The attribute's ValidationAttribute. ErrorMessage element defines the text of the error message if validation fails. Starting with the.

NET makes it easy to localize error messages. Error messages will be localized if:. The ValidationAttribute.

ErrorMessage is provided in the validation attribute. The name of the localized resources file has the form DataAnnotation.

The key name of the resource is the string assigned to the ValidationAttribute. ErrorMessage attribute, and its value is the localized error message.

For example, the following data annotation attribute defines the default culture's error message for an invalid rating. You can then create a resource file, DataAnnotation.

The file must be found in the App. LocalResources folder. For example, the following is the key and its value in a localized French fr language error message:.

In addition, data annotation localization is extensible. Developers can plug in their own string localizer provider by implementing the IStringLocalizerProvider interface to store localization string somewhere other than in a resource file.

NET now allows task-returning methods to be used with session-state store providers, thereby allowing ASP. NET apps to get the scalability benefits of async.

To supports asynchronous operations with session state store providers, ASP. NET includes a new interface, System.

ISessionStateModule , which inherits from IHttpModule and allows developers to implement their own session-state module and async session store providers.

The interface is defined as follows:. Providers that implement these methods reduce thread-blocking on a web server and improve the scalability of an ASP.

NET service. OutputCacheProviderAsync class, which inherits from System. OutputCacheProvider and allows developers to implement an asynchronous output-cache provider.

The OutputCacheUtility class, which provides helper methods for configuring the output cache. HttpCachePolicy class. In the System. Characters in the.

Support for Unicode 8. These include the StringInfo class, the overloaded Char. GetUnicodeCategory method, and the character classes recognized by the.

NET Framework regular expression engine. Character and string comparison and sorting is unaffected by this change and continues to rely on the underlying operating system or, on Windows 7 systems, on character data provided by the.

For changes in character categories from Unicode 6. For changes from Unicode 7. In addition to supporting the larger key sizes of FIPS , the.

FIPS support is provided by the new System. DSACng class. In keeping with recent changes to the RSA class in. NET Framework 3. The inputs to the routines, and the routines themselves, were configured via properties on the ECDiffieHellmanCng object.

But since not every routine read every input property, there was ample room for confusion on the past of the developer. To address this in the. The Windows cryptography library CNG added support for storing persisted symmetric keys and using hardware-stored symmetric keys, and the.

Since the notion of key names and key providers is implementation-specific, using this feature requires utilizing the constructor of the concrete implementation types instead of the preferred factory approach such as calling Aes.

Any programs that have registered a custom SignatureDescription handler into CryptoConfig to add support for these algorithms will continue to function as they did in the past, but since there are now platform defaults, the CryptoConfig registration is no longer necessary.

SqlClient includes the following new features in the. When connection pooling is enabled and a timeout or other login error occurs, an exception is cached, and the cached exception is thrown on any subsequent connection attempt for the next 5 seconds to 1 minute.

This behavior is not desirable when connecting to Azure SQL Databases, since connection attempts can fail with transient errors that are typically recovered quickly.

To better optimize the connection retry experience, the connection pool blocking period behavior is removed when connections to Azure SQL Databases fail.

The addition of the new PoolBlockingPeriod keyword lets you select the blocking period best suited for your app.

Values include:. The connection pool blocking period for an application that connects to an Azure SQL Database is disabled, and the connection pool blocking period for an application that connects to any other SQL Server instance is enabled.

This is the default value. To improve performance of parameterized queries against encrypted database columns, encryption metadata for query parameters is now cached.

With the SqlConnection. ColumnEncryptionQueryMetadataCacheEnabled property set to true which is the default value , if the same query is called multiple times, the client retrieves parameter metadata from the server only once.

Column encryption key entries in the key cache are now evicted after a configurable time interval, set using the SqlConnection.

ColumnEncryptionKeyCacheTtl property. In the. When an application targets the. For applications that target the. Better support for multiple daylight saving time adjustment rules by the DataContractJsonSerializer class.

Customers can use an application configuration setting to determine whether the DataContractJsonSerializer class supports multiple adjustment rules for a single time zone.

This is an opt-in feature. To enable it, add the following setting to your app. TimeZoneInfo supports multiple adjustment rules, which makes it possible to work with historic time zone data; TimeZone does not.

WCF has a new app setting that can be set on client applications to ensure they always connect to the service listening on the URI that best matches the one that they request.

With this app setting set to false the default , it is possible for clients using NetNamedPipeBinding to attempt to connect to a service listening on a URI that is a substring of the requested URI.

For example, a client tries to connect to a service listening at net. With this app setting set to false , the client would attempt to connect to the wrong service.

After setting the app setting to true , the client will always connect to the best matching service. Clients using NetNamedPipeBinding find services based on the service's base address if it exists rather than the full endpoint address.

To ensure this setting always works the service should use a unique base address. To enable this change, add the following app setting to your client application's App.

In most cases, there should be no impact to existing apps, because TLS 1. All existing clients should be able to negotiate a connection using at least TLS 1.

If Ssl3 is required, use one of the following configuration mechanisms to add it to the list of negotiated protocols. SslProtocols property.

The TcpTransportSecurity. An application that uses a CollectionView object to group data can now explicitly declare how to sort the groups.

Explicit sorting addresses the problem of non-intuitive ordering that occurs when an app dynamically adds or removes groups, or when it changes the value of item properties involved in grouping.

It can also improve the performance of the group creation process by moving comparisons of the grouping properties from the sort of the full collection to the sort of the groups.

To support group sorting, the new GroupDescription. SortDescriptions and GroupDescription. CustomSort properties describe how to sort the collection of groups produced by the GroupDescription object.

This is analogous to the way the identically named ListCollectionView properties describe how to sort the data items. For example, the following XAML groups data by age, sort the age groups in ascending order, and group the items within each age group by last name.

Touch keyboard support enables focus tracking in WPF applications by automatically invoking and dismissing the touch Keyboard in Windows 10 when the touch input is received by a control that can take textual input.

In previous versions of. In other words, the application's UI is scaled by the OS as appropriate, depending on the DPI of the monitor on which the app is rendered.

For apps running under the. For more information, see the Windows Workflow Foundation blog. Availability of IntelliSense when a customer rebuilds a workflow project from Visual Studio In versions of the.

NET Framework prior to 4. While the project build is successful, the workflow types are not found on the designer, and warnings from IntelliSense for the missing workflow types appear in the Error List window.

To enable this scenario, you must make the following change to your app. If this scenario is not enabled, running the application continues to generate an exception with the message, "This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.

PrepareForUpdate method. In versions of the. NET Framework before. PrepareForUpdate can result in the following issues:. Id is at the end of the line.

Flowchart Activity Designer or other Workflow Activity Designers may display all objects in their default locations as opposed to attached property values.

ClickOnce has been updated to support TLS 1. ClickOnce automatically detects which protocol is required; no extra steps within the ClickOnce application are required to enable TLS 1.

This technology acts as a bridge by enabling you to gradually migrate your existing code base to UWP, thereby bringing your app to all Windows 10 devices.

The app continues to behave as before and runs as a full trust app. Once the app is converted, an app container process can be added to the existing full trust process to add an adaptive user interface.

When all functionality is moved to the app container process, the full trust process can be removed and the new UWP app can be made available to all Windows 10 devices.

The unmanaged debugging API has been enhanced in the. This enables debuggers to do some code flow analysis when a NullReferenceException occurs and to work backwards to determine the managed variable that corresponds to the native location that was null.

Application Compatibility in 4. NET Framework implementation wraps calls into existing Windows functionality. The following example code shows how easy it is to generate a signature for a byte stream by using the new support for ECDSA X certificates included in the.

With this support, customers can leverage asymmetric keys stored in HSMs without having to write custom column master key store providers and registering them in applications.

It transparently detects whether your application is connecting to an AlwaysOn availability group AG on a different subnet and quickly discovers the current active server and provides a connection to the server.

Without setting the connection keyword to true , an application might experience a timeout while connecting to an AlwaysOn Availability Group.

With this release, an application does not need to set MultiSubnetFailover to true anymore. The delay in firing touch events has been fixed in the.

In addition, typing in a RichTextBox control no longer ties up the render thread during fast input. The spell checker in WPF has been updated on Windows 8.

There is no change in functionality on Windows versions prior to Windows 8. As in previous versions of the. This capability is available in addition to the ability to register them per-control.

They are supported on Windows 8. The following rules apply to these files:. The files should have extensions of.

Each line should consist of a word in the added and excluded word lists , or an autocorrect pair with the words separated by a vertical bar " " in the AutoCorrect word list.

Help us improve our samples by sending us a pull-request or opening a GitHub issue. The code for this package has been open sourced and is available on GitHub.

The Transaction. If this operation is successful, there are limitations placed on the capabilities of the transaction. Once a non-MSDTC transaction promoter is enlisted, it must be used for future durable enlistments by using protocols that it defines.

The Guid of the transaction promoter can be obtained by using the PromoterType property. When the transaction promotes, the transaction promoter provides a Byte array that represents the promoted token.

Users of the new Transaction. EnlistPromotableSinglePhase IPromotableSinglePhaseNotification, Guid overload must follow a specific call sequence in order for the promotion operation to complete successfully.

These rules are documented in the method's documentation. In ASP. NET Core, it is becoming much more common for assemblies to be compiled in-memory by Roslyn.

For developers making profiling tools, this means that PDBs that historically were serialized on disk may no longer be present. Profiler tools often use PDBs to map code back to source lines for tasks such as code coverage or line-by-line performance analysis.

Previously such tools could instrument IL at any time, but metadata could only be modified at module load time.

Because IL refers to metadata, this limited the kinds of instrumentation that could be done. This change makes a much broader range of on-the-fly instrumentation possible.

Cross-machine event tracing allows customers to profile a program on Machine A and look at the profiling data with source line mapping on Machine B.

Using previous versions of the. NET Framework, the user would copy all the modules and native images from the profiled machine to the analysis machine that contains the IL PDB to create the source-to-native mapping.

While this process may work well when the files are relatively small, such as for phone applications, the files can be very large on desktop systems and require significant time to copy.

Combining both mappings provides a source-to-native mapping. Since the native image PDB is much smaller than all the modules and native images, the process of copying from Machine A to Machine B is much faster.

NET introduces the. NET Core. Some new features apply to both, and other features are specific to. NET Core, which is a lean. NET implementation for building modern cloud-based apps.

NET Core is modular so you can include only those features that are needed in your application.

It can be hosted on IIS or self-hosted in a custom process, and you can run apps with different versions of the.

NET Framework on the same server. It includes a new environment configuration system that is designed for cloud deployment. You build ASP.

Your existing applications will work on the new. For information, see ASP. The Model Binding system now supports Task -returning model binding methods.

This feature allows Web Forms developers to get the scalability benefits of async with the ease of the data-binding system when using newer versions of ORMs, including the Entity Framework.

Async model binding is controlled by the aspnet:EnableAsyncModelBinding configuration setting. On apps the target the. On apps running on the.

NET Framework, it is false by default. It can be enabled by setting the configuration setting to true. NET in. HttpClient API. The browser and the web server IIS on Windows do all the work.

You don't have to do any heavy-lifting for your users. Microsoft and Google have been collaborating on a new approach to authentication, called the Token Binding Protocol.

The premise is that authentication tokens in your browser cache can be stolen and used by criminals to access otherwise secure resources for example, your bank account without requiring your password or any other privileged knowledge.

The new protocol aims to mitigate this problem. The Token Binding Protocol will be implemented in Windows 10 as a browser feature. NET apps will participate in the protocol, so that authentication tokens are validated to be legitimate.

The client and the server implementations establish the end-to-end protection specified by the protocol.

However, it was not supported by ASP. NET features depended on a stable hash code. With Always Encrypted, SQL Server can perform operations on encrypted data, and best of all the encryption key resides with the application inside the customer's trusted environment and not on the server.

Always Encrypted secures customer data so DBAs do not have access to plain text data. Encryption and decryption of data happens transparently at the driver level, minimizing changes that have to be made to existing applications.

The new bit compiler provides significant performance improvements over the older bit JIT compiler. The new bit compiler is enabled for bit processes running on top of.

Your app will run in a bit process if it is compiled as bit or AnyCPU and is running on a bit operating system. While care has been taken to make the transition to the new compiler as transparent as possible, changes in behavior are possible.

Numerics namespace, which can yield good performance improvements. The assembly loader now uses memory more efficiently by unloading IL assemblies after a corresponding NGEN image is loaded.

This change decreases virtual memory, which is particularly beneficial for large bit apps such as Visual Studio , and also saves physical memory.

Many new APIs have been added around to. These include the following changes and additions:. The CultureInfo. CurrentCulture and CultureInfo.

CurrentUICulture properties are now read-write rather than read-only. If you assign a new CultureInfo object to these properties, the current thread culture defined by the Thread.

CurrentCulture property and the current UI thread culture defined by the Thread. CurrentUICulture properties also change.

A new overload of the GC. Collect Int32, GCCollectionMode, Boolean, Boolean method allows you to control whether both the small object heap and the large object heap are swept and compacted or swept only.

Previous versions of the. Cryptography implementation. We have had requests to support the CNG API, since it supports modern cryptography algorithms , which are important for certain categories of apps.

A set of extension methods for X Certificates, System. XCertificate2 and System. Some smartcards, etc.

For example, encrypting data using an XCertificate2 object requires code like the following in previous versions of the.

Code that uses the new cryptography APIs in. The following new methods have been added to the DateTimeOffset structure to support converting date and time values to or from Unix time:.

Check that the file's SHA hash matches phpMyAdmin needs your continued support to grow and thrive phpMyAdmin would not exist without the work of many volunteers and contractors.

InputAttributes and CheckBox. LabelAttributes that are programmatically added to a WebForms CheckBox control are lost after postback.

For the correct behavior for restoring attributes on postback, set the targetFrameworkVersion to 4. In applications that target. Net might incorrectly parse multipart boundary values, resulting in form data being unavailable during request execution.

Applications that target. Starting with applications running on. When targeting previous framework versions or not using targetFrameworkVersion , trailing delimiters for some values are still returned.

Form HttpRequest. Files HttpRequest. ValidationAttribute , the ValidationContext. MemberName property returns null. Starting with.

Add the following setting to your web. A bug in the. PageIndexChanging to sometimes not fire for System.

GridView s that have enabled System. This issue has been fixed in the. NET Framework. GridView is on the last page and Last System. PageSize is different from System.

Alternatively, the app can be modified to allow paging instead of custom paging , as that scenario does not demonstrate the problem.

In the. With this change the SafeArray is now marshalled successfully. When using a WinRT event with a. In previous versions of the. If enabling the QI for IAgileObject breaks execution, you can disable this code by setting the following configuration.

This might be just a single console session, or it might affect the entire machine if you set the environment variable globally. The environment variable name is not case-sensitive.

Method 2: Registry Using Registry Editor regedit. EXE tool to add this value from a command-line or scripting environment. The registry value name is not case-sensitive.

NetDataContractSerializer cannot be deserialized in the. Note that moving in the other direction serializing with the. Similarly, all 4. Serializing and deserializing with a single version of the.

NET Framework is not affected. If it is necessary to serialize and deserialize a System. DataContractSerializer or System.

BinaryFormatter serializer should be used instead of the System. Alternatively, because this issue is addressed in the. In System.

The behavior will change only when all of the following are true: The URI has the scheme file: and is followed by four or more slashes. The host name begins with an underscore or other non-reserved symbol.

The URI contains Unicode characters. Applications working with URIs consistently containing Unicode could have conceivably used this behavior to disallow references to UNC shares.

Those applications should use IsUnc instead. Prior to the. Beginning in the. Dynamic bases will still differ for different apps; this change only removes the random naming element for different instances of the same app.

If a random base is needed, it must be produced in your app's code rather than via this API. Be aware that GetCustomAttribute s will work more frequently now.

If an app was previously relying on the System. AmbiguousMatchException , reflection should now be used to explicitly look for multiple indexers, instead.

NET Framework v4. This issue is fixed beginning in the. ETW EventListeners with a blank keyword mask do not properly capture events from providers with explicit keywords.

Alternatively, this issue has been fixed in the. Starting with the. PersianCalendar class uses the Hijri solar algorithm.

Converting dates between the System. PersianCalendar and other calendars may produce a slightly different result beginning with the.

Also, PersianCalendar. Be aware that some early or late dates may be slightly different when using the PersianCalendar in. Also, when serializing dates between processes which may run on different.

NET Framework versions, do not store them as PersianCalendar date strings since those values may be different.

Reflection objects can no longer be passed from managed code to out-of-process DCOM clients. The following types are affected: System.

Assembly System. MemberInfo and its derived types, including System. FieldInfo , System. MethodInfo , System. Type , and System.

TypeInfo System. MethodBody System. Module System. The URI must contain percent-encoded Unicode or unreserved symbols.

Absolute when creating a URI. TryCreate Uri, String, Uri. The System. TargetFrameworkName was previously null in the default app domain, unless it was explicitly set.

Beginning in 4. TargetFrameworkName property for the default app domain will have a default value derived from the TargetFrameworkAttribute if one is present.

Non-default app domains will continue to inherit their System. TargetFrameworkName from the default app domain which will not default to null in 4.

Code should be updated to not depend on TargetFrameworkName defaulting to null. If it is required that this property continue to evaluate to null, it can be explicitly set to that value.

Now, the method will succeed and return a valid string that omits the inaccessible portions of the certificate.

Any code depending on XCertificate2. ToString Boolean should be updated to expect that the returned string may exclude some certificate data such as public key, private key, and extensions in some cases in which the API would have previously thrown.

ToString Boolean. Attempts to retry connection open requests will occur almost immediately after transient connection errors. This change allows the connection open attempt to be retried immediately for Azure SQL databases, thereby improving the performance of cloud- enabled apps.

The connection pool blocking feature means that the app cannot connect to the database for an extensive period, even though the database is available and the app needs to render within a few seconds.

If this behavior is undesirable, the connection pool blocking period can be configured by setting the System.

OpenAsync SqlConnection. Open SqlConnection. OpenAsync CancellationToken. Also, this issue has been fixed in the. When requesting Unicode character categories in.

NET Framework versions. This change mostly affects Cherokee syllables and New Tai Lue vowels signs and tone marks. GetUnicodeCategory String, Int String representations of System.

ContentDisposition 's have been updated, beginning in 4. DateTime with two digits. This causes ToString to return a slightly different string in 4. Note that ContentDispositions are sometimes serialized via converting them to strings, so any ToString operations, serialization, or GetHashCode calls should be reviewed.

Do not expect that string representations of ContentDispositions from different. NET Framework versions will correctly compare to one another.

Convert the strings back to ContentDispositions, if possible, before conducting a comparison. ToString ContentDisposition. With this improvement, client certificates that are used to authenticate to a server must be configured for client authentication.

Similarly server certificates that are for the authenticating a server must be configured for server authentication. With this change, if the root certificate is disabled, the certificate chain validation fails.

The same change was also made to. NET Framework 3. You can find more information here. This change is on by default and can be turned off by a configuration setting.

It now returns false for any verification failure. CryptographicException if the signature itself is badly formatted. Any code whose execution depends on handling the System.

CryptographicException should instead execute if validation fails and the method returns False. SignedXml and System. EncryptedXml lead to different run-time behaviors.

For example, If a document has multiple elements with the same id attribute and a signature targets one of those elements as the root of the signature, the document will now be considered invalid.

Documents using non-canonical XPath transform algorithms in references are now considered invalid.

Documents using non-canonical XSLT transform algorithms in references are now consider invalid. Any program making use of external resource detached signatures will be unable to do so.

Developers might want to review the usage of XmlDsigXsltTransform and XmlDsigXsltTransform , as well as types derived from Transform since a document receiver may not be able to process it.

Transform System. DataContractJsonSerializer fails to serialize or deserialize due to missing 'known types' has been clarified. Apps should not depend on specific exception messages.

If an app depends on this message, either update it to expect the new message or preferably change it to depend only on the exception type.

Product versioning has changed from the previous releases of the. NET Framework, and particularly from the. NET Framework 4, 4.

The file and product versioning for. NET Framework files has changed from the earlier versioning scheme of 4. You can see these new values when you view the file's Properties after right-clicking on a file.

Version property returns the fixed version string 4. For some applications, notifications are fired too close to the configured limits to allow for useful reactions.

Developers can now write their own memory monitors to replace the default by using the ApplicationMonitors. MemoryMonitor property.

Memory Limit Reactions. By default, ASP. NET attempts to trim the object cache and periodically call GC. Collect when the private byte process limit is near.

For some applications, the frequency of calls to GC. Collect or the amount of cache that is trimmed are inefficient. Developers can now replace or supplement the default behavior by subscribing IObserver implementations to the application's memory monitor.

Ability to configure the default message security settings to TLS 1. This is an opt-in setting; to enable it, you must add the following entry to your application configuration file:.

WCF includes a number of code changes that eliminate race conditions, thereby improving performance and the reliability of serialization options.

Starting with applications that target. Dynamic DPI changes the layout and appearance of forms and controls when the user changes the DPI or display scale factor of a running application.

This is an opt-in feature in. For the impact of this change on application compatibility, see the Application compatibility section. For more information, see Announcing.

Data annotation validators enable you to perform validation by adding one or more attributes to a class property. The attribute's ValidationAttribute.

ErrorMessage element defines the text of the error message if validation fails. Starting with the. NET makes it easy to localize error messages.

Error messages will be localized if:. The ValidationAttribute. ErrorMessage is provided in the validation attribute. The name of the localized resources file has the form DataAnnotation.

The key name of the resource is the string assigned to the ValidationAttribute. ErrorMessage attribute, and its value is the localized error message.

For example, the following data annotation attribute defines the default culture's error message for an invalid rating.

You can then create a resource file, DataAnnotation. The file must be found in the App. LocalResources folder. For example, the following is the key and its value in a localized French fr language error message:.

In addition, data annotation localization is extensible. Developers can plug in their own string localizer provider by implementing the IStringLocalizerProvider interface to store localization string somewhere other than in a resource file.

NET now allows task-returning methods to be used with session-state store providers, thereby allowing ASP.

NET apps to get the scalability benefits of async. To supports asynchronous operations with session state store providers, ASP. NET includes a new interface, System.

ISessionStateModule , which inherits from IHttpModule and allows developers to implement their own session-state module and async session store providers.

The interface is defined as follows:. Providers that implement these methods reduce thread-blocking on a web server and improve the scalability of an ASP.

NET service. OutputCacheProviderAsync class, which inherits from System. OutputCacheProvider and allows developers to implement an asynchronous output-cache provider.

The OutputCacheUtility class, which provides helper methods for configuring the output cache. HttpCachePolicy class. In the System. Characters in the.

Support for Unicode 8. These include the StringInfo class, the overloaded Char. GetUnicodeCategory method, and the character classes recognized by the.

NET Framework regular expression engine. Character and string comparison and sorting is unaffected by this change and continues to rely on the underlying operating system or, on Windows 7 systems, on character data provided by the.

For changes in character categories from Unicode 6. For changes from Unicode 7. In addition to supporting the larger key sizes of FIPS , the.

FIPS support is provided by the new System. DSACng class. In keeping with recent changes to the RSA class in. NET Framework 3. The inputs to the routines, and the routines themselves, were configured via properties on the ECDiffieHellmanCng object.

But since not every routine read every input property, there was ample room for confusion on the past of the developer. To address this in the.

The Windows cryptography library CNG added support for storing persisted symmetric keys and using hardware-stored symmetric keys, and the.

Since the notion of key names and key providers is implementation-specific, using this feature requires utilizing the constructor of the concrete implementation types instead of the preferred factory approach such as calling Aes.

Any programs that have registered a custom SignatureDescription handler into CryptoConfig to add support for these algorithms will continue to function as they did in the past, but since there are now platform defaults, the CryptoConfig registration is no longer necessary.

SqlClient includes the following new features in the. When connection pooling is enabled and a timeout or other login error occurs, an exception is cached, and the cached exception is thrown on any subsequent connection attempt for the next 5 seconds to 1 minute.

This behavior is not desirable when connecting to Azure SQL Databases, since connection attempts can fail with transient errors that are typically recovered quickly.

To better optimize the connection retry experience, the connection pool blocking period behavior is removed when connections to Azure SQL Databases fail.

The addition of the new PoolBlockingPeriod keyword lets you select the blocking period best suited for your app.

Values include:. The connection pool blocking period for an application that connects to an Azure SQL Database is disabled, and the connection pool blocking period for an application that connects to any other SQL Server instance is enabled.

This is the default value. To improve performance of parameterized queries against encrypted database columns, encryption metadata for query parameters is now cached.

With the SqlConnection. ColumnEncryptionQueryMetadataCacheEnabled property set to true which is the default value , if the same query is called multiple times, the client retrieves parameter metadata from the server only once.

Column encryption key entries in the key cache are now evicted after a configurable time interval, set using the SqlConnection.

ColumnEncryptionKeyCacheTtl property. In the. When an application targets the. For applications that target the. Better support for multiple daylight saving time adjustment rules by the DataContractJsonSerializer class.

Customers can use an application configuration setting to determine whether the DataContractJsonSerializer class supports multiple adjustment rules for a single time zone.

This is an opt-in feature. To enable it, add the following setting to your app. TimeZoneInfo supports multiple adjustment rules, which makes it possible to work with historic time zone data; TimeZone does not.

WCF has a new app setting that can be set on client applications to ensure they always connect to the service listening on the URI that best matches the one that they request.

With this app setting set to false the default , it is possible for clients using NetNamedPipeBinding to attempt to connect to a service listening on a URI that is a substring of the requested URI.

For example, a client tries to connect to a service listening at net. With this app setting set to false , the client would attempt to connect to the wrong service.

After setting the app setting to true , the client will always connect to the best matching service. Clients using NetNamedPipeBinding find services based on the service's base address if it exists rather than the full endpoint address.

To ensure this setting always works the service should use a unique base address. To enable this change, add the following app setting to your client application's App.

In most cases, there should be no impact to existing apps, because TLS 1. All existing clients should be able to negotiate a connection using at least TLS 1.

If Ssl3 is required, use one of the following configuration mechanisms to add it to the list of negotiated protocols. SslProtocols property.

The TcpTransportSecurity. An application that uses a CollectionView object to group data can now explicitly declare how to sort the groups. Explicit sorting addresses the problem of non-intuitive ordering that occurs when an app dynamically adds or removes groups, or when it changes the value of item properties involved in grouping.

It can also improve the performance of the group creation process by moving comparisons of the grouping properties from the sort of the full collection to the sort of the groups.

To support group sorting, the new GroupDescription. SortDescriptions and GroupDescription. CustomSort properties describe how to sort the collection of groups produced by the GroupDescription object.

This is analogous to the way the identically named ListCollectionView properties describe how to sort the data items.

For example, the following XAML groups data by age, sort the age groups in ascending order, and group the items within each age group by last name.

Touch keyboard support enables focus tracking in WPF applications by automatically invoking and dismissing the touch Keyboard in Windows 10 when the touch input is received by a control that can take textual input.

In previous versions of. In other words, the application's UI is scaled by the OS as appropriate, depending on the DPI of the monitor on which the app is rendered.

For apps running under the. For more information, see the Windows Workflow Foundation blog. Availability of IntelliSense when a customer rebuilds a workflow project from Visual Studio In versions of the.

NET Framework prior to 4. While the project build is successful, the workflow types are not found on the designer, and warnings from IntelliSense for the missing workflow types appear in the Error List window.

To enable this scenario, you must make the following change to your app. If this scenario is not enabled, running the application continues to generate an exception with the message, "This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.

PrepareForUpdate method. In versions of the. NET Framework before. PrepareForUpdate can result in the following issues:. Id is at the end of the line.

Flowchart Activity Designer or other Workflow Activity Designers may display all objects in their default locations as opposed to attached property values.

ClickOnce has been updated to support TLS 1. ClickOnce automatically detects which protocol is required; no extra steps within the ClickOnce application are required to enable TLS 1.

This technology acts as a bridge by enabling you to gradually migrate your existing code base to UWP, thereby bringing your app to all Windows 10 devices.

The app continues to behave as before and runs as a full trust app. Once the app is converted, an app container process can be added to the existing full trust process to add an adaptive user interface.

When all functionality is moved to the app container process, the full trust process can be removed and the new UWP app can be made available to all Windows 10 devices.

The unmanaged debugging API has been enhanced in the. This enables debuggers to do some code flow analysis when a NullReferenceException occurs and to work backwards to determine the managed variable that corresponds to the native location that was null.

Application Compatibility in 4. NET Framework implementation wraps calls into existing Windows functionality. The following example code shows how easy it is to generate a signature for a byte stream by using the new support for ECDSA X certificates included in the.

With this support, customers can leverage asymmetric keys stored in HSMs without having to write custom column master key store providers and registering them in applications.

It transparently detects whether your application is connecting to an AlwaysOn availability group AG on a different subnet and quickly discovers the current active server and provides a connection to the server.

Without setting the connection keyword to true , an application might experience a timeout while connecting to an AlwaysOn Availability Group.

With this release, an application does not need to set MultiSubnetFailover to true anymore. The delay in firing touch events has been fixed in the.

In addition, typing in a RichTextBox control no longer ties up the render thread during fast input. The spell checker in WPF has been updated on Windows 8.

There is no change in functionality on Windows versions prior to Windows 8. As in previous versions of the. This capability is available in addition to the ability to register them per-control.

They are supported on Windows 8. The following rules apply to these files:. The files should have extensions of.

Each line should consist of a word in the added and excluded word lists , or an autocorrect pair with the words separated by a vertical bar " " in the AutoCorrect word list.

Help us improve our samples by sending us a pull-request or opening a GitHub issue. The code for this package has been open sourced and is available on GitHub.

The Transaction. If this operation is successful, there are limitations placed on the capabilities of the transaction.

Once a non-MSDTC transaction promoter is enlisted, it must be used for future durable enlistments by using protocols that it defines.

The Guid of the transaction promoter can be obtained by using the PromoterType property. When the transaction promotes, the transaction promoter provides a Byte array that represents the promoted token.

Users of the new Transaction. EnlistPromotableSinglePhase IPromotableSinglePhaseNotification, Guid overload must follow a specific call sequence in order for the promotion operation to complete successfully.

These rules are documented in the method's documentation. In ASP. NET Core, it is becoming much more common for assemblies to be compiled in-memory by Roslyn.

For developers making profiling tools, this means that PDBs that historically were serialized on disk may no longer be present. Profiler tools often use PDBs to map code back to source lines for tasks such as code coverage or line-by-line performance analysis.

Previously such tools could instrument IL at any time, but metadata could only be modified at module load time.

Because IL refers to metadata, this limited the kinds of instrumentation that could be done. This change makes a much broader range of on-the-fly instrumentation possible.

Cross-machine event tracing allows customers to profile a program on Machine A and look at the profiling data with source line mapping on Machine B.

Using previous versions of the. NET Framework, the user would copy all the modules and native images from the profiled machine to the analysis machine that contains the IL PDB to create the source-to-native mapping.

While this process may work well when the files are relatively small, such as for phone applications, the files can be very large on desktop systems and require significant time to copy.

Combining both mappings provides a source-to-native mapping. Since the native image PDB is much smaller than all the modules and native images, the process of copying from Machine A to Machine B is much faster.

NET introduces the. NET Core. Some new features apply to both, and other features are specific to. NET Core, which is a lean.

NET implementation for building modern cloud-based apps. NET Core is modular so you can include only those features that are needed in your application.

It can be hosted on IIS or self-hosted in a custom process, and you can run apps with different versions of the.

NET Framework on the same server. It includes a new environment configuration system that is designed for cloud deployment. You build ASP.

Your existing applications will work on the new. For information, see ASP. The Model Binding system now supports Task -returning model binding methods.

This feature allows Web Forms developers to get the scalability benefits of async with the ease of the data-binding system when using newer versions of ORMs, including the Entity Framework.

Async model binding is controlled by the aspnet:EnableAsyncModelBinding configuration setting. On apps the target the. On apps running on the.

NET Framework, it is false by default. It can be enabled by setting the configuration setting to true. NET in. HttpClient API. The browser and the web server IIS on Windows do all the work.

You don't have to do any heavy-lifting for your users. Microsoft and Google have been collaborating on a new approach to authentication, called the Token Binding Protocol.

The premise is that authentication tokens in your browser cache can be stolen and used by criminals to access otherwise secure resources for example, your bank account without requiring your password or any other privileged knowledge.

The new protocol aims to mitigate this problem. The Token Binding Protocol will be implemented in Windows 10 as a browser feature.

NET apps will participate in the protocol, so that authentication tokens are validated to be legitimate. The client and the server implementations establish the end-to-end protection specified by the protocol.

However, it was not supported by ASP. NET features depended on a stable hash code. With Always Encrypted, SQL Server can perform operations on encrypted data, and best of all the encryption key resides with the application inside the customer's trusted environment and not on the server.

Always Encrypted secures customer data so DBAs do not have access to plain text data. Encryption and decryption of data happens transparently at the driver level, minimizing changes that have to be made to existing applications.

The new bit compiler provides significant performance improvements over the older bit JIT compiler. The new bit compiler is enabled for bit processes running on top of.

Your app will run in a bit process if it is compiled as bit or AnyCPU and is running on a bit operating system.

While care has been taken to make the transition to the new compiler as transparent as possible, changes in behavior are possible. Numerics namespace, which can yield good performance improvements.

The assembly loader now uses memory more efficiently by unloading IL assemblies after a corresponding NGEN image is loaded.

This change decreases virtual memory, which is particularly beneficial for large bit apps such as Visual Studio , and also saves physical memory.

Many new APIs have been added around to. These include the following changes and additions:. The CultureInfo. CurrentCulture and CultureInfo.

CurrentUICulture properties are now read-write rather than read-only. If you assign a new CultureInfo object to these properties, the current thread culture defined by the Thread.

CurrentCulture property and the current UI thread culture defined by the Thread. CurrentUICulture properties also change. A new overload of the GC.

Collect Int32, GCCollectionMode, Boolean, Boolean method allows you to control whether both the small object heap and the large object heap are swept and compacted or swept only.

Previous versions of the. Cryptography implementation. We have had requests to support the CNG API, since it supports modern cryptography algorithms , which are important for certain categories of apps.

A set of extension methods for X Certificates, System. XCertificate2 and System. Some smartcards, etc. For example, encrypting data using an XCertificate2 object requires code like the following in previous versions of the.

Code that uses the new cryptography APIs in. The following new methods have been added to the DateTimeOffset structure to support converting date and time values to or from Unix time:.

The AppContext class adds a new compatibility feature that enables library writers to provide a uniform opt-out mechanism for new functionality for their users.

It establishes a loosely coupled contract between components in order to communicate an opt-out request. This capability is typically important when a change is made to existing functionality.

Conversely, there is already an implicit opt-in for new functionality. With AppContext , libraries define and expose compatibility switches, while code that depends on them can set those switches to affect the library behavior.

By default, libraries provide the new functionality, and they only alter it that is, they provide the previous functionality if the switch is set.

An application or a library can declare the value of a switch which is always a Boolean value that a dependent library defines.

The switch is always implicitly false. Setting the switch to true enables it. Explicitly setting the switch to false provides the new behavior.

The library must check if a consumer has declared the value of the switch and then appropriately act on it. It's beneficial to use a consistent format for switches, since they are a formal contract exposed by a library.

The following are two obvious formats. For apps that target the. The behavior of apps that target previous versions of the. NET Framework, or that do not target a specific version of the.

NET Framework, is unaffected. For more information, see the "Culture and task-based asynchronous operations" section of the CultureInfo class topic.

It can be used to persist data across threads. Value property was explicitly changed, or because the thread encountered a context transition.

Three convenience methods, Task. CompletedTask , Task. FromCanceled , and Task. FromException , have been added to the task-based asynchronous pattern TAP to return completed tasks in a particular state.

You now can use the EventSource class to log administrative or operational messages to the event log, in addition to any existing ETW sessions created on the machine.

In the past, you had to use the Microsoft. EventSource NuGet package for this functionality. This functionality is now built-into.

Allows specially attributed classes and arrays as well as primitive types to be passed as a payload. Causes Start and Stop events to tag events between them with an ID that represents all currently active activities.

To support these features, the overloaded Write method has been added to the EventSource class. Changes have been made to layout rounding to reduce instances of clipping in controls with borders.

By default, this feature is enabled only if your TargetFrameworkAttribute is set to. NET 4. Applications that target earlier versions of the framework but are running on the.

Support for automatically loading the right cursor based on DPI setting has been added to System. Customer reports on Connect that touch produces unpredictable behavior have been addressed in the.

WPF in the. This allows you to create non-rectangular and transparent child windows in your top-level windows. You can enable this feature by setting the HwndSourceParameters.

UsesPerPixelTransparency property to true. It is now possible to select which protocol to use, or to disable old lesser secure protocols.

This can be done either by setting the SslProtocols property or by adding the following to a configuration file.

There are two ways to do this:. Users can specify a string that WCF will use as a prefix for the connection group name. Two messages with different prefixes are sent using different underlying HTTP connections.

Properties property. Users can also enable a feature that ensures that messages sent using channels created by different channel factories will use different underlying HTTP connections.

To enable this feature, users must set the following appSetting to true :. You can now specify the number of seconds a workflow service will hold on to an out-of-order operation request when there is an outstanding "non-protocol" bookmark before timing out the request.

A "non-protocol" bookmark is a bookmark that is not related to outstanding Receive activities. Some activities create non-protocol bookmarks within their implementation, so it may not be obvious that a non-protocol bookmark exists.

These include State and Pick. So if you have a workflow service implemented with a state machine or containing a Pick activity, you will most likely have non-protocol bookmarks.

You specify the interval by adding a line like the following to the appSettings section of your app. The default value is 60 seconds.

If value is set to 0, out-of-order requests are immediately rejected with a fault with text that looks like this:.

This is the same message that you receive if an out-of-order operation message is received and there are no non-protocol bookmarks. If the value of the FilterResumeTimeoutInSeconds element is non-zero, there are non-protocol bookmarks, and the timeout interval expires, the operation fails with a timeout message.

You can now include the distributed transaction identifier for the transaction that has caused an exception derived from TransactionException to be thrown.

You do this by adding the following key to the appSettings section of your app. Windows 10 includes a new high-scalability networking algorithm that makes better use of machine resources by reusing local ports for outbound TCP connections.

NET apps to take advantage of the new behavior. In previous versions of Windows, there was an artificial concurrent connection limit typically 16,, the default size of the dynamic port range , which could limit the scalability of a service by causing port exhaustion when under load.

SocketOptionName enumeration value. The ServicePointManager. ReusePort property. By default, the ServicePointManager.

ReusePort property to true. Developers writing a sockets-only application can specify the System. SocketOptionName option when calling a method such as Socket.

SetSocketOption so that outbound sockets reuse local ports during binding. A new property, IdnHost , has been added to the Uri class to better support international domain names and PunyCode.

This feature has been expanded in. NET Core primarily supports the Unicode encodings and by default provides limited support for code page encodings.

You can add support for code page encodings available in. NET Framework but unsupported in. NET Core by registering code page encodings with the Encoding.

RegisterProvider method. For more information, see System. Windows apps for Windows 10 that target. They produce apps characterized by faster startup and execution times.

For more information, see Compiling Apps with. NET Native. For an overview of. NET Native and Compilation. Your apps are compiled to native code by default when you compile them with Visual Studio or later.

For more information, see Getting Started with. To support debugging. Http namespace are now available as open-source packages on GitHub. To access the code, see.

NET on GitHub. For more information and how to contribute to these packages, see. NET apps. The new HttpResponse.

AddOnSendingHeaders methods let you inspect and modify response headers and status code as the response is being flushed to the client app.

The HostingEnvironment. QueueBackgroundWorkItem method lets you schedule small background work items.

NET tracks these items and prevents IIS from abruptly terminating the worker process until all background work items have completed.

This method can't be called outside an ASP. NET managed app domain. HeadersWritten and HttpResponseBase. HeadersWritten properties return Boolean values that indicate whether the response headers have been written.

StatusCode which throw exceptions if the headers have been written will succeed. Resizing in Windows Forms controls. This feature has been expanded.

You can now use the system DPI setting to resize components of the following additional controls for example, the drop-down arrow in combo boxes :.

New workflow feature. PromoteAndEnlistDurable method to request the following:. This can be done within the same app domain, and doesn't require any extra unmanaged code to interact with MSDTC to perform the promotion.

The new method can be called only when there's an outstanding call from System. Transactions to the IPromotableSinglePhaseNotification Promote method that's implemented by the promotable enlistment.

Profiling improvements. The following new unmanaged profiling APIs provide more robust profiling:. Previous ICorProfiler implementations supported lazy loading of dependent assemblies.

The new profiling APIs require dependent assemblies that are injected by the profiler to be loadable immediately, instead of being loaded after the app is fully initialized.

Debugging improvements. The following new unmanaged debugging APIs provide better integration with a profiler. You can now access metadata inserted by the profiler as well as local variables and code produced by compiler ReJIT requests when dump debugging.

Event tracing changes. This enables Advanced Power Management APM vendors to provide lightweight tools that accurately track the costs of individual requests and activities that cross threads.

The method may be used by an enlistment that was previously created by Transaction. Promote method. It asks System. Transactions to promote the transaction to an MSDTC transaction and to "convert" the promotable enlistment to a durable enlistment.

After this method completes successfully, the IPromotableSinglePhaseNotification interface will no longer be referenced by System.
