Summary

Security improvements

There are no new security improvements in this release. This update is cumulative and contains all previously released security improvements.

Quality and reliability improvements

WPF1- Addresses an issue where WPF does not respond to touch if the WPF window was activated by a touch manipulation (e.g. swiping a listbox).
– Adds a mitigation for an issue involving tearing, flickering, or incorrect composition of visual content under high GPU-load conditions.
– Addresses an issue where the extra information associated with a WM_KEYDOWN message is discarded before the handlers for the PreviewKeyDown or KeyDown events can retrieve it via GetMessageExtraInfo.
– Addresses an issue where AutomationElement.FindFirst or FindAll do not search the subtree of an hwnd whose UIA_WindowVisibilityOverridden property is set to 1.
– Addresses an issue where a binding on TextBox.Text with UpdateSourceTrigger=PropertyChanged produces incorrect results when the Microsoft Quick IME is used.SQL Connectivity- Under certain error cases caused due to NullReferenceException thrown while populating SqlParameter values using customer provided delegates, the SqlClient driver may not cleanup the state of connection state. The connection in bad state, can make its way into the connection pool and may be picked up for reuse causing unexpected failures on the connection. If such a condition is recognized, an AppContext Switch “Switch.System.Data.SqlClient.CleanupParserOnAllFailures”, may be enabled to clean up connections on any kind of failures even while running into errors with delegates.WCF2- Addresses a failure to correctly timeout a failed request when making an asynchronous WCF call over HTTP. If the service has sent a partial response message and fails to send the remainder of the response, the client may not fail the call after the configured timeout.1 Windows Presentation Foundation (WPF)
2 Windows Communication Foundation (WCF)
