[621651]<\/li>\n<li>In certain .NET applications, timing issues in the finalizer thread could potentially cause exceptions during AppDomain or process shutdown. This is generally seen in applications that do not correctly shut down Dispatchers running on worker threads prior to process or AppDomain shutdown. Such applications should take care to properly manage the lifetime of Dispatchers. This change adds an AppContext switch that can help alleviate (but not eliminate) some of the issues that may arise from these application design issues. To enable this, set the AppContext flag &#8220;Switch.MS.Internal.DoNotInvokeInWeakEventTableShutdownListener=true&#8221;.
