If you have an ASP.NET website running on a 32-bit version of the .NET Framework 4.6 or AMD64 version of the .NET Framework 4.6 platform with RyuJit disabled, you may experience w3wp crash because of unhandled ThreadAbortException.
When the crash happens, you can see the following log in Windows Event Log:
Application ID: [ApplicationID]
Process ID: [ProcessID]
Message: Thread was being aborted.

Assume that you have a WCF client connecting to the WCF service by using WCF Routing Service. If the end service raises any unexpected exception that's not a type of FaultException or the configure changes, WCF Routing Service may not route subsequent requests to the end service.
When this issue occurs, you receive the following exception:

This is an update to support the new Georgian Lari symbol. The country of Georgia has introduced a new currency symbol for the Lari, but the currency name isn't changed. The new currency symbol has also been added to the Unicode standard. This update makes sure that the correct currency symbol is displayed by the .NET Framework based on system locale settings.
If a Gen2 collection occurs during Parallel.ForEach calls, you may experience long hangs after you install Visual Studio 2015 or the .NET Framework 4.6 without Visual Studio.
This update updates the Garbage Collector by resolving system freezes caused by this issue.
After you install the .NET Framework 4.6, the DateTime.Parse and Date.TryParse methods don’t work correctly. This issue may occur with the following culture settings:
This update enables DateTime.Parse and Date.TryParse to function correctly in cultures that are using the same date and time separator.
After you install the .NET Framework 4.6, the .NET Framework 4.6 uses a new 64-bit compiler that's called RyuJIT. In some cases, the new compiler generates incorrect code that causes unpredictable behavior or crashes.
This update fixes many issues in the RyuJIT compiler. If the application still behaves unpredictably after the installation of this update, see additional detailed troubleshooting guidance.
If it's determined that RyuJIT may be involved in your issue by following the troubleshooting steps at the link, please log the issue at http://connect.microsoft.com. Include as much detail as possible in the report and also code to reproduce the issue.
