Hello folks,

this has been reported in Wine-Staging first, shamelessly cloning it here for
discussion and raise awareness of this insufficiency in Wine loader.

https://bugs.wine-staging.com/show_bug.cgi?id=190

Requires 64-bit WINEPREFIX as the main .NET executable is 64-bit.

--- snip ---
$ wine ./still\ -\ coronoid.exe 
err:process:start_process L"Z:\home\focht\Downloads\still - coronoid\still
- coronoid.exe" doesn't have an entry point, it cannot be executed
--- snip ---

--- snip ---
$ file *.{dll,exe}
Core.dll:             PE32 executable (DLL) (console) Intel 80386 Mono/.Net
assembly, for MS Windows
still - coronoid.exe: PE32+ executable (GUI) x86-64 Mono/.Net assembly, for MS
Windows
--- snip ---

The patch by Michael:

https://github.com/wine-compholio/wine-staging/tree/master/patches/ntdll-CLI...
("Implement proper handling of CLI .NET images in Wine library loader")

For Wine-Mono bits ('mscoree._CorValidateImage') I'll create an extra ticket.
