Hello,

after upgrading an existing .NET Framework 4.0 WINEPREFIX with .NET Framework
4.5 (dev preview) some simple apps that previously worked failed to run.

I created a simple C# based .NET "hello world" console app using the provided
C# compiler (csc.exe) in .NET 4.0 prefix and it fails to execute after .NET 4.5
CLR upgrade:

It seems there is an improved integration of error reporting with WER.

Adding a stub returning E_NOTIMPL doesn't make the CLR happy:

You have to return S_OK to please the CLR.
With that change "hello world" runs again. Yay!
