title: Visual Studio 2013 sp1 hangs when trying to debug ASP.NET web site?
body: <p>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.</p>
  
  <p>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.</p>
  
  <p>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:</p>
  
  <p><a href="https://stackoverflow.com/questions/19932980/visual-studio-2013-crashes-and-restarts-every-time-i-run-my-test-solution">Visual Studio 2013 crashes and restarts every time I run my test solution</a></p>
  
  <p>But I triple-checked and I do have the 64-bit option checked.  What can I do to fix this?</p>
