Yes, I'm not sure if C# has the program name in argv[0] or not - so maybe that 
needs adding before calling the C++ method that is expecting it to be there.

Yes, stuff like the hard coded result is there just to demonstrate that it's 
possible to return a result back to C#. I'll try and post an explanation of 
what it's all about, and what is missing when I've time - it is very similar 
to qtruby though, so it won't do any harm to look at that code.
