Several security and quality updates were rolled out on 11th Jan 2022 as a part of the monthly patch rollout for Windows. Along with those, the KB5008876 .Net Framework update for Windows 10 21H1, 20H2 is also here. This patch brings in a bunch of important fixes and updates aimed at resolving a lot of previously known issues as well as improving the overall user experience. As of now, there are no known issues in this .net framework patch.
In this article, we will be looking at all highlights and all the various improvements in KB5008876 for Windows 10 21H2, 21H1, 20H2.
.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.

Microsoft .net framework is a software development framework and ecosystem designed and supported by Microsoft to allow building and running applications on windows. It works on two major components, common language runtime (CLR) that handles running apps, the .NET Framework Class Library, which provides a library of tested, reusable code that developers can call from their own apps. With windows 11 and windows 11 2022 update Microsoft has released .NET Framework 4.8.1 and is available for download and install. The latest .net framework 4.8 update brings a number of bug fixes, security patches, and improvements to the Common Language Runtime, ASP.Net, Windows Forms, Windows Presentation Foundation, and Windows Communication Foundation.
If you’ve upgraded or installed windows 11 or windows 10 22H2 you don’t need to install it as it comes included with the new version of Windows. However, users using Windows 7 SP1, Windows 8.1 and Older Windows 10 versions can download and install .NET Framework version 4.8.1 on their computers. Since Microsoft prefers .NET 4.8.1 distribution via the web installer, it is difficult to find working offline installer links.

.NET Framework 4.8 Changelog
The latest NET Framework 4.8.1 includes native support for the Arm64 architecture (Windows 11+) and accessibility improvements as well as other improvements. Here is the complete changelog listed official site.
Native support for Arm64
- Add native Arm64 support to the .NET Framework family to leverage the benefits of running workloads natively on Arm64 for better performance when compared to running x64 code emulated on Arm64.
Accessible Tooltips
- tooltips now comply with the guidelines set forth in the WCAG2.1 content on Hover or Focus guidance. The requirements for tooltips require the following:
- Tooltips must display either via mouse hover or by keyboard navigation to the control.
- Tooltips should be dismissable. That is, a simple keyboard command like the ESC key should dismiss the tooltip.
- Tooltips should be hoverable. Users should be able to place their mouse cursor over the tooltip. This enables scenarios like using magnifier to be able to read the tooltip for low-vision users.
- Tooltips should be persistent. Tooltips should not automatically disappear after a certain time has elapsed. Rather, the tooltips should be dismissed by the user moving their mouse to another control, or by dismissing the tooltip as described above.
Windows Forms
- Added support for the UIA Text Pattern to enable assistive technology to traverse the content of a TextBox or similar text-based control letter by letter.
- Fixed high contrast issues in several controls and have changed the contrast ratio of selection rectangles to be darker and more visible.
- Fixed several DataGridView issues:
- Updated the scrollbar names for consistency.
- Fixed an issue where Narrator was unable to focus on empty DataGridView cells.
- Enabled developers to set the localized control type property for Custom DataGridView cells.
- Updated the link color for DataGridViewLink cells to have better contrast with the background.
