Issues that this hotfix rollup fixes

Issue 1

It’s an update to support the new Georgian Lari symbol. The country of Georgia has introduced a new currency symbol for the Lari, but the currency name isn't changed.The new Georgian Lari symbol has also been added to the Unicode standard. This update makes sure that the correct currency symbol is displayed by the .NET Framework based on system locale settings. ​

Issue 2

This 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 3.0 Service Pack 2 on your computer, install the corresponding fix for your version to fix this issue.
