Recently, Visual Studio 2013 started hanging again when trying to debug/trace an ASP.NET web site. The site was created with WebMatrix 3 but I don't think that is relevant.
When VS2013 opens the web site Solution it takes a really long time to load up. Once it does load up and I run the project, it hits my first breakpoint and then the IDE Window quickly shows "(not responding)" in the title bar and the IDE is now hung.
This happened to me a long time ago and the root cause was needing to set the "use 64-bit IIS" option as indicated by this SO post:
Visual Studio 2013 crashes and restarts every time I run my test solution
But I triple-checked and I do have the 64-bit option checked. What can I do to fix this?
Note, I can run the project if I don't debug using Ctrl-F5. The hang happens when a breakpoint is set. It seems like whatever communication VS2013 has to have with IIS Express when it sets breakpoint isn't happening properly, and VS2013 is waiting without time-out for an answer. But that's just speculation.
