Hello folks,

required for bug 38661 in case Wine-Mono is used (default).
You don't need this when MS .NET Framework is present in prefix.

Patch with semi-impl by Michael available in Wine-Staging:

https://github.com/wine-compholio/wine-staging/tree/master/patches/mscoree-CorValidateImage

I did some further research and found interesting discussions about the details
