My source files end up with .h (C++ is different from C#), i have never seen XML sourcecode before. But it looks good.
I found you use schemas.microsoft.com/VisualStudio
Is that a XMLcompiler and/or where can i get a compiler for your codes.
I lolled when i discovered this in the files "project is exposed to COM"
However, on running the program i get a warning, it's Dutch , it says Can't initialize, aborting.
