I have a simple gtk# mono app running on windows. It works fine on my PC which has Mono, .NET, and GTK installed. But if I give the exe to a friend it obviously doesn't work.

Mono's mkbundle tool doesn't seem to work on windows without an enormous amount of hassle (I've tried). So I've reverted to the quick solution of just including the necessary DLL's with the exe when giving it to a friend. 

But I don't know what is required. My guesses so far have been wrong. I tried including everything that mkbundle wanted to embed, but that didn't work. Is there some tool that can tell me what I need?
