title: "Unable to start debugging" - VS2010 ASP.NET MVC 2
body: <p>I can launch debug session only once with VS2010 and ASP.NET MVC2. When I end the first session and try to launch another I can see...</p>
  
  <p>"Unable to start debugging" - no other messages, I'm using Visual Studio Development Server instead of IIS, Windows 7 64-bit</p>
  
  <p>I can add that few days ago I was working on Windows XP and everything was fine.</p>
  
  <ul>
  <li>I've tried running as admin (I thought there are any privileges issues) - no result</li>
  <li>checked <a href="http://msdn.microsoft.com/en-us/library/dwesw3ee%28VS.71%29.aspx#vxtbshttpservererrorsthingstocheck" rel="noreferrer">http://msdn.microsoft.com/en-us/library/dwesw3ee%28VS.71%29.aspx#vxtbshttpservererrorsthingstocheck</a> (this page refers to IIS settings and I'm not using IIS)</li>
  <li>I'm not satisfied with manually attaching - VS2010 is expensive IDE, it HAS TO work in this situation</li>
  </ul>
  
  <p>Does anyone have some conclusions?</p>
