Please note that if you want to use good ol' C++, aka without the CLR and completely unmanaged code, make sure that it's a Win32 project under the C++ project types. If it says .Net in it, then the code compiles for use with the CLR and is fully managed. That means that if you require MFC or ATL, you should use the Win32 projects, and if you want to use System.Windows.Forms you should use .Net.
Hope that helps!
