Quality and reliability improvements

For ASP.NET

ASP.NET sequentially executes requests that have the same SessionID. This means that you may see the requests collecting in the queue if there are lots of concurrent requests that have the same SessionID. After you apply this fix, you can limit the number of the requests in the queue through the following appSettings entry:

<appSettings>
   <add key="aspnet:RequestQueueLimitPerSession" value="50"/>
</appSettings>

 

For CLR

If you arrange an array of struct A and an array of struct B as SAFEARRAY, and struct A and struct B have identical GUIDs, a memory leak may occur.

Note This update also contains cumulative updates that were released previously starting on October 11, 2016.
