Visual Studio 2015 c++ breakpoint will not be hit

Question

Hi I have a c++ app in visual studio 2015. My .exe's pdb wont work and it cant hit breakpoints. when I open the modules window, the status says Symbol format not supported. my debug file flag is /ZI in the projects settings. I've tried deleting the object and bin folders. When I create a new project, it hits the breakpoint. Any ideas?

I had use managed compatibility mode and use native compatibility mode both checked. Unchecking use native compatibility mode fixed it.
