I dont know if this is the same linking error that I encountered once, but any way try to delete the debug folder from your project, you will find 2 debug folders inside your project, delete the inner one then rebuild your solution.

Inside C# used to be good, but there's no 2.0 version. I'd look for a Microsoft Press book, tho, just choose whatever seems to be aimed at your level.

thanks for your help:)

You are welcome :) Really, consider the C++/CLI board for future CLI-related questions. I get so confused trying to think in .NET when I'm on the C++ board. Cheers! Mark "flailing in the dark" Salsbery ;)
