How do I step through a method in an unmanaged DLL when loaded from a managed project? (Visual C++/C#)

I have a Visual Studio 2010 solution with 3 projects. The first is an unmanaged DLL project (C++) that I've written with a few DLL exports. The second project is a Managed wrapper for the first project (C# using DLLImport). The final project is a WPF application I'm using to test out the functionality of the first projects.

I'm using the first project by copying the DLL in a post-build step to the release/debug folder of the wrapper. However, this isn't enough to allow me to step through it in the debugger. I can't figure out how to reference the project properly so that I'm loading debug symbols for the unmanaged DLL. How would I do this?

Try enabling unmanaged code debugging:

  2. Click the Debug tab.

  3. Select the Enable unmanaged code debugging check box.
