.Net Framework update KB5008876 changes
Here is the changelog –
- KB5008876 addresses a problem where an attack by unauthenticated users could cause a DOS on an affected system.
- The patch also attempts to resolve a concern whereby WPF doesn’t respond to touch sometimes. It is noticed to be happening if the WPF window was activated by a touch manipulation, as in the case of swiping a Listbox.
- This patch also features the solution for an issue that involves flickering, tearing or incorrect composition, etc. of the display content when under high GPU-load conditions.
- KB5008882 also brings a potential resolution against yet another problem. Earlier the extra information associated with a WM_KEYDOWN message sometimes used to get discarded before the handlers for the PreviewKeyDown or KeyDown events can retrieve it via GetMessageExtraInfo.
- It addresses an issue where FindAll or AutomationElement.FindFirst does not search the subtree of a hand whose UIA_WindowVisibilityOverridden property has been set to 1.
- Yet another concern that this patch attempts to resolve is to include the one where the binding is on TextBox.Text with UpdateSourceTrigger=PropertyChanged ends up with incorrect results when the Microsoft Quick IME is in use.
- There are certain improvements pertaining to SQL connectivity as well. In case of certain errors resulting from NullReferenceException thrown when loading SqlParameter values with the aid of customer-provided delegates, the SqlClient driver may be prevented from cleaning up the state of connection state. The end result would be unexpected failures on the connection. It is pointed out that if you recognize such a condition, you may enable an AppContext Switch “Switch.System.Data.SqlClient.CleanupParserOnAllFailures”, to clean up connections on any kind of failures.
- Finally, it also offers some improvement to a failure to properly timeout an unsuccessful request when making an asynchronous WCF call over HTTP.
