Notice
July 18, 2017 This update is referenced in the July 2017 Preview of the Quality Rollups for the .NET Framework 3.5, 4.5.2, 4.6, 4.6.1, 4.6.2, and 4.7 for Windows Server 2012 that is dated July 18, 2017. This Quality Rollup contains no new updates.
Introduction
This May 2017 update for Windows Server 2012 includes cumulative reliability improvements in the .NET Framework 3.5. 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 from October 11, 2016.
