UPDATE 4/12:


February 15, 2022 - KB5010474 Cumulative Update Preview for .NET Framework 3.5 and 4.8 for Windows 11​


The February 15, 2022 update for Windows 11 includes cumulative reliability improvements in .NET Framework 3.5 and 4.8. We recommend that you apply this update as part of your regular maintenance routines. Before you install this update, see the Prerequisites and Restart requirement sections.

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

Winforms- Addresses a leak of IRawElementProviderSimple objects which was introduced in .NET Framework 4.8. This is an opt-in fix, add the following compatibility switch to the app.config file in order to dispose the accessible objects:
<runtime>

<!-- AppContextSwitchOverrides values are in the form of 'key1=true|false;key2=true|false -->

<AppContextSwitchOverrides value="Switch.System.Windows.Forms.DisconnectUiaProvidersOnWmDestroy=true"/>

</runtime>
Note: that when the accessibility server application opts into this fix, the accessibility client will receive errors when accessing the disconnected provider. This is expected because the corresponding control window is destroyed. Previous behavior where the provider was returning information for destroyed controls was incorrect.
NET Libraries- Addresses an issue when Ssl negotiation can hang indefinitely when client certificates are used when TLS 1.3 is negotiated. Before the change renegotiation (PostHandshakeAuthentiction) would fail and SslStream or HttpWebRequest would observe a timeout.
