How do I enable JIT debugging with my SW addin?  I followed the instructions on the "your add-in is crashing" box and inserted the following in my app.config

I also don't have any build configurations active other than Debug, so as far as I can tell my project should be compiling with debugging enabled.  I can't even get SW to recognize when I put breakpoints in my code, however, so I assume I'm missing a step.

I am using Visual Studio 2012 Professional and SolidWorks 2012 x64.
