Visual Studio Crashes when changing an AndroidResource file.

[dellis1972]

Context Developer Community 1038779:

There is a known issue in 16.7 Preview 1 where Visual Studio will crash unexpectedly when a Xamarin.Android project is in the solution. The issue on appears on projects which set the AndroidUseManagedDesignTimeResourceGenerator MSbuild property to False.

<AndroidUseManagedDesignTimeResourceGenerator>False</AndroidUseManagedDesignTimeResourceGenerator>

Workaround.

For now setting AndroidUseManagedDesignTimeResourceGenerator to True or removing the element completely fixes the issue.

Cause

As part of the effort to improve build times 16.7 Preview 1 uses the newer aapt2 daemon mode to compile resources. As part of this we need to set the InputEncoding for the process to be UTF8. This is so that paths which contain accents or special characters are interpreted correctly by aapt2. For some reason when doing a background Design Time build setting the InputEncoding is failing with the following exception.

System.IO.IOException: The handle is invalid.
