Why do I always get an HTTP 500 - Internal Server Error when debugging a web app under IIS 7.5

I am trying to get Orchard CMS running under IIS, but I keep getting an HTTP 500 response. I have built and run the source code from within VS2012, but even with exceptions set to break when thrown, VS doesn't break, and I still get a very unhelpful and opaque HTTP 500 response.

I created a new web site called Orchard, pointing to the source folder of the web app, i.e. C:\Development\Orchard.Source.1.6\src\Orchard.Web, and bound it to host name orchard.local, which I added to my hosts file under 127.0.0.1. I have read that I need to set file system permissions for IIS_IUSRS when running the web site under IIS; I don't know if I still do for debugging under VS. I would have though VS would take care of that. Then, for some reason I don't have that group, I only have an IIS_WPG group, which is supposed to be for IIS6.

How can I diagnose what is causing this Internal Server Error if I can't even get VS to break on the exception?
