Does it generate files, but doesn't add them visibly to the solution?
Version of Visual Studio?
Still haven't got it to work?
Do the contract files inherit IContract from the right assembly and are decorated with [AddInContract]?
If all fails: if you would d/l source, build in debug mode and put a breakpoint at the code that starts writing files, what is the state of the program?
Is it possible to reproduce for me in some way?
