Windows Store: IL2CPP does not support plugins targeting .NET 4.0+ or referencing Windows Runtime

Windows Store Apps

-

At this point in time, using IL2CPP scripting backend on Windows Store limits your assemblies to targeting up to .NET 3.5 (the same limit that applies to all other Unity platforms including the editor). Trying to use DLLs compiled against .NET 4.0 or higher or DLLs that reference .winmd files (i.e. Windows Runtime APIs) will cause build to fail by UnusedBytecodeStripper2.exe crashing with one of the following errors:

AssemblyResolutionException: Failed to resolve assembly: 'System.Runtime, Version=4.0.20.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

AssemblyResolutionException: Failed to resolve assembly: 'Windows, Version=255.255.255.255, Culture=neutral, PublicKeyToken=null'

The only workaround is marking these plugins as not compatible with Windows Store IL2CPP scripting backend.
