title: ASP.NET MVC3 project throws immediate 404 when run locally in Visual Studio
body: <p>When I run my ASP.NET MVC3 app locally in VS2010, it is throwing an immediate 404. This project used to work previously and I'm tearing my hair out to figure out what's going on. </p>
  
  <p>The error message is:</p>
  
  <pre><code>Server Error in '/' Application.
  
  The resource cannot be found.
  
  Description: HTTP 404. The resource you are looking for (or one of its
  dependencies) could have been removed, had its name changed, or is 
  temporarily unavailable.  Please review the following URL and make sure that 
  it is spelled correctly.

  <p>I've tried setting breakpoints in the controller but it's never hit.  I have no idea how to debug or fix this. Any suggestions?</p>
