Answer 1

Mono does not support mixed-mode assemblies on non-Windows operating systems.

Remove your C++ wrapper and rewrite your application to only use P/Invoke to call into native code.

Answer 2

Compile your project in Visual Studio, but enable the following compiler options:

• /clr:pure: This will make a pure CLR assembly (without any x86/x86-64 asm), that should run on mono, unless you use some C runtime calls (CRT).
• /clr:safe: The same as pure, but you can't have CRT references, so your project might not compile. If it doesn't, replace those function calls with other portable calls.

The resulting assembly should be pure CLR and will work with Mono.
