c# - VS2015 Project wont run in debug mode

Not a duplicate of: VS2015 Project no longer runs in debug mode

My issue is the same though, except I have already tried the solutions from that question. Things I have tried/checked:

• Optimize Code is not checked



• Config Manager is set to Build and Debug


• Define DEBUG and TRACE constant is checked


• Cleaning / Rebuilding


• Changing the above settings, saving, changing back.


• Deleting the DLL it complains about being in debug mode and recompiling.

I have no idea what else to check. Any ideas?
