MFC + C# .NET Compilation

[ziadn]

I am working on Microsoft Visual Studio 2005 C++ using MFC and I need to join to my solution the C# project that uses a DLL file which is compiled using .NET framework. Now in the MFC, which is unmanaged code, I tried to include the DLL file and called the function from C# using the "gcroot" function. It worked and compiled perfectly but when I run the project, it crashes as soon as it tries to access the DLL file.

Any solution or suggestions on how to make this work?
