.NET Framework May 2017 Cumulative Quality Update for Windows 10
We just released a new Cumulative Quality Update for the .NET Framework. This update is specific to Windows 10 Creators Update.
Previously released security and quality updates are included in this release.
These quality updates will be made available to other .NET Framework and Windows version combinations in Q3 2017. You can read the .NET Framework Monthly Rollups Explained to learn more about how the .NET Framework is updated.
This release contains the security improvements included in the NET Framework May 2017 Security and Quality Rollup.
The following improvements are included in this release.
Some applications using the managed C++ memcpy intrinsic could execute incorrectly. The JIT compiler when optimizing code that contains a C++ memcpy intrinsic could generate incorrect code.
Some applications terminate with an A/V in clrjit.dll.The JIT compiler when optimizing a block of unreachable code could hit a A/V which results in the unexpected early termination of the application.
If two WPF applications that target Side by Side (SxS) .NET versions (3.5 and 4.X) are loaded in the same process issues can occur on touch/stylus enabled machines. A common example of this is loading VSTO add-ins written in WPF. This is due to an issue with choosing the correct PenIMC.dll version for each application. This fix allows WPF to properly differentiate between both DLLs and function correctly.
