Issue that this hotfix rollup fixesThis hotfix rollup fixes an issue with touch-enabled Windows Presentation Foundations (WPF) applications that are running in the same process but targeting two different .NET Framework versions. An example of this issue is two VSTO Office Add-ins written in WPF but targeted to different side-by-side .NET Frameworks. Users in this scenario could see strange touch behavior and/or crashes at various points during program execution.
The fix makes sure that proper DLLs are loaded and accessed in these scenarios, stopping any issues with touch behavior or program crashes.
Note If you use the .NET Framework 4.0 or the .NET Framework 4.5.2 on your computer, install the corresponding fix for your version to fix this issue.
Known issuesA fix that was previously released for touch-enabled VSTO add-ins in WPF was found to have a regression in scenarios in which partial-trust applications are used on touch-enabled devices. In these scenarios, customers see an application crash and cannot load a partial trust application. Therefore, the fix for touch-enabled VSTO add-ins has been removed.
