I work with VS2005. I managed to add to my C# solution a C++ MFC regular dll project. I added win32 functions and managed to export them to the c# code and call them with the interoperability machanism. Trying to debug the unmanaged code I saw that I simply jump across it and never jump into it. Is there a way to do it? Regards Ronny

Ronny, You need to enable mixed native & managed debugging for the project that you start debugging - it's an option in the property pages somewhere. Dave
