What is new in .NET Framework 4.6.2?
.NET Framework 4.6.2
On August 2, 2016, Microsoft announced the release of .NET Framework 4.6.2. In summary the following list presents what are newly added into Microsoft .NET Framework:
1. Soft Keyboard Support (Note: Soft Keyboard support enables automatic invocation and dismissal of the touch keyboard in WPF applications without disabling WPF stylus/touch support on Windows 10.)
2. OperationContext.Current Async Improvements (Note: WCF now has the ability to include OperationContext.Current with ExecutionContext so that the OperationContext flows through asynchronous continuations. With this improvement, WCF allows CurrentContext to propagate from one thread to another thread. This means that even if there’s a context switch between calls to OperationContext.Current, it’s value will flow correctly throughout the execution of the method.)
3. Transport Security for Windows Cryptography Library (CNG)
4. TransportDefaults No Longer Supports SSL 3
5. DataContractJsonSerializer Improvements (Note: The DataContractJsonSerializer has been improved to better support multiple daylight saving time adjustment rules. When enabled, DataContractJsonSerializer will use the TimeZoneInfo class instead of the TimeZone class. The TimeZoneInfo class supports multiple adjustment rules, which makes it possible to work with historic time zone data. This is useful when a time zone has different daylight saving time adjustment rules, such as (UTC+2) Istanbul.)
6. NetNamedPipeBinding Best Match (Note: In .NET 4.6.2, NetNamedPipeBinding has been enhanced to support a new pipe lookup, known as “Best Match”. When using “Best Match”, the NetNamedPipeBinding service will force clients to search for the service listening at the best matching URI to their requested endpoint, rather than the first matching service found.)
7. Always Encrypted Enhancements (Note: Always Encrypted is a feature designed to protect sensitive data, such as credit card numbers or national identification numbers that are stored in a database. It allows clients to encrypt sensitive data inside client applications, never revealing the encryption keys to the database engine. As a result, Always Encrypted provides a separation between those who own the data (and can view it) and those who manage the data [but should have no access]. The .NET Framework Data Provider for SQL Server (System.Data.SqlClient) introduces two important enhancements for Always Encrypted around performance and security.)
8. Performance (Note: To improve performance of parameterized queries against encrypted database columns, encryption metadata for query parameters is now cached. Database clients retrieve parameter metadata from the server only once when theSqlConnection::ColumnEncryptionQueryMetadataCacheEnabled property is set to true (the default), even if the same query is called multiple times.)
9. Security (Note: Column encryption key entries in the key cache are now evicted after a configurable time interval. The time interval can be set using the SqlConnection::ColumnEncryptionKeyCacheTtl property.)
10. Async Improvements (Note: SessionStateModule and Output-Cache Module have been improved to enable async scenarios. The team is working on releasing async versions of both modules via NuGet, which will need to be imported into an existing project. Both NuGet packages are anticipated to release within the coming weeks.)
11. SessionStateModule Interfaces (Note: Session State allows you to store and retrieve user session data as a user navigates an ASP.NET site. You can now create your own async Session State Module implementation using the new ISessionStateModule interface, enabling you to store session data in your own way and use async methods.)
12. Output-Cache Module (Note: Output Caching can dramatically improve the performance of an ASP.NET application by caching the result returned from a controller action to avoid unnecessarily generating the same content for every request. You can now use async APIs with Output Caching by implementing a new interface called OutputCacheProviderAsync. Doing so will reduce thread-blocking on a web server and improve scalability of an ASP.NET service.)
13. DataAnnotation Localization (Note: Localization is now much easier when using model binding and DataAnnotiation validation. ASP.NET has adopted a simple convention for resx resource files that contain DataAnnotation validation messages: a) Located in the App_LocalResources folder and b) Follow the DataAnnotation.Localization.{locale}.resx naming convention.)
14. Long Path Support (MAXPATH)
15. X509 Certificates Now Support FIPS 186-3 Digital Signature Algorithm
16. Improved Usability of Elliptic Curve Diffie-Hellman Key Derivation Routines
17. Support for Persisted-Key Symmetric Encryption
18. SignedXml Support for SHA-2 Hashing
19. NullReferenceException Improvements (Note: You have probably experienced and investigated the cause of a NullReferenceException.)
20. Transport Layer Security (TLS) 1.1 and 1.2 Support
21. Client Certificate Support
22. Per-Monitor DPI Support
23. Group Sorting (Note: An application that requests a CollectionView to group data can now explicitly declare how to sort the groups. This overcomes some unintuitive ordering that can arise when the application dynamically adds or removes groups, or when the application 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.)

* Changed in .Net 4.6.2: Fixed potential periodic hangs or poor performance of a WPF application running on a device that has touch support. This is mostly seen when running over a touch-enabled remote desktop or other touch enabled remote access solutions. [146399]
* Changed in .Net 4.6.2: Enable automatic invocation and dismissal of the touch keyboard in WPF applications without disabling WPF stylus/touch support on Windows 10 [178044]
* Changed in .Net 4.6.2: Fixed missing glyph symbol display issues for those WPF applications that render text in the following ranges using a font that does not contain these ranges. [165725] Ranges: Unicode = "0000-052F, 0590-06FF, 0750-077F, 08A0-08FF, 1D00-1FFF, 2C60-2C7F, A720-A7FF, FB00-FB0F, FB1D-FBFF" Unicode = "FC00-FDCF, FDF0-FDFF, FE20-FE2F, FE70-FEFE"
* Changed in .Net 4.6.2: Developers of WPF applications on .NET 4.6.1 may notice that the number of promotions from a touch move event to a mouse move event do not correspond 1:1. This change ensures that there is a corresponding mouse move promotion for every applicable touch move. [169470]
* Changed in .Net 4.6.2: Enable WPF Applications to look and feel great in multi DPI environments. This means crisper text, sharper images and general polish. [191569]
* Changed in .Net 4.6.2: WPF applications that allocate large numbers of bitmaps over time can possibly see performance issues such as frequent pauses and large numbers of garbage collections. This fix changes the bitmap garbage collection strategy to help alleviate these issues. [121913]
* Changed in .Net 4.6.2: Enables enumeration of generic and themed ResourceDictionary instances, and provides a notification infrastructure for listening to loading and unloading of ResourceDictionary instances. [159740]
* Changed in .Net 4.6.2: Starting .NET 4.6, CurrentCulture or CurrentUICulture changes made by event handlers (or any other method that WPF orchestrates the dispatch for) are lost when the method completes. This can result in various unintended side-effects ranging from the selection of incorrect UI language by application code, to potential loss of state information. This fix addresses the bug described above. [157919]
* Changed in .Net 4.6.2: Fixed compilation error in situations when a locally defined custom type in a XAML resource dictionary is immediately followed by something like x:Array. [131561]
* Changed in .Net 4.6.2: Long runs of dashes are now displayed correctly, without spurious spaces. [92892]

* Changed in .Net 4.6.2: Developers can opt-in to receiving an exception when TextBoxBase controls fail to complete a Copy or Cut operation. [177621]
* Changed in .Net 4.6.2: WPF applications being used via multi-touch enabled devices could sometimes lose mouse promotion after a multi-touch drag/drop. This occurred when users removed touch points other than the primary (or dragging) touch point first. Doing so would cause an incorrect count of active touch devices causing mouse promotion handling to be incorrect for future touch interaction. This is now fixed. [185548]
* Changed in .Net 4.6.2: WPF would previously throw an ArgumentException when a UI Automation Client queried for an unknown TextAttribute. This was causing performance issues in WPF applications on Windows 8 and above. WPF will now simply return NotSupported in response to querying an unknown TextAttribute preserving the external behavior and helping alleviate performance issues. [187764]
* Changed in .Net 4.6.2: Fix for crash that occurs when: App is running more than one dispatcher thread, First thread uses any ItemsControl, Second thread uses a Selector. While something is selected, the underlying collection raises a Reset event, or the ItemsSource changes. [190507]
* Changed in .Net 4.6.2: Per Monitor DPI Aware apps now can have their title bars scaled to the correct DPI when an app is moved from one DPI to a different one. [206796]
* Changed in .Net 4.6.2: Images created with BitmapCreateOptions=DelayCreation can now update their ImageSource by listening to the RoutedEvent DpiChanged on the Image. This event is fired before the Image is decoded, and thus the cost of decoding the image twice can be avoided. [206986]
* Changed in .Net 4.6.2: WPF apps which are Per monitor DPI aware, running on Windows 10 Anniversary Update, will not have their popup windows like Menus clipped the first time they are open on a monitor with a different DPI. [212426]
* Changed in .Net 4.6.2: Fixed for Wisptis doesn't support some scenarios in Windows 7, trying to load wisptis in certain scenarios can result in delays upon start or crashes. [215016]
* Changed in .Net 4.6.2: Fixed issues with the touch keyboard showing on controls when it should not. [222625]
