Introduction


This May 2017 Update for Windows Server 2008 Service Pack 2 includes cumulative reliability improvements in the .NET Framework 2.0 Service Pack 2. 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.

Important

  • If you install a language pack after you install this update, you must reinstall this update. Therefore, we recommend that you install any language packs that you need before you install this update. For more information, see Add language packs to Windows.

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.
