I can only think of three projects that had > needed them in the history of Mono. I've done some work on this. And actually I managed to run mixed-mode assemblies. Note that it is only possible on Windows because native code is usually platform (arch and OS as well) dependent. I implemented support for loading image files using LoadLibrary so that the NT loader will take care of the image patching. I also had to patch the in-memory image of mscoree.dll so that export address table point to functions in mono.dll that is required for LoadLibrary support. This also will enable Wine (and Windows is someone is willing to replace or modify his on-disk mscoree.dll image) to execute managed images using CreateProcess without creating a mono.exe child process. This was the hardest part. IJW thunks (managed-to-native) are really P/Invoke methods with function RVA stored in method body RVA so it was very easy to implement, I only had to remove code preventing IJW from work. V-table fixups (native-to-managed) are not difficult either but requires it's own wrapper methods so my current implementation probably will need improvements. Note that this still will not make Mono able to use MSVCRT because that uses unmanaged API of .NET Framework that isn't implemented by Mono. I am stilll working on a cleaned-up patch but will send to the list soon.
