title: Visual Studio 2010 giving error "External Component has thrown an exception"
body: <p>I am running Visual Studio Ultimate on Windows 7. Here is the description of my problem:</p>
  
  <ul>
  <li><p>My VS 2010 had been running absolutely fine until today when it started giving error "<strong>External Component has thrown an exception</strong>" when I try to open a new website. Creating a new web application works fine though but I am unable to run any of them. </p></li>
  <li><p>While trying to run the previously created websites/webapps, its giving error as "<strong>Unable to launch ASP.NET development server</strong>".</p></li>
  <li><p>And when I try to debug the website/web app, I am getting error: "Unable to launch ASP.NET development server. <strong>An attempt was made to perform an initialization operation when initialization has already been completed</strong>". </p></li>
  <li><p>Similar errors are coming when I try to open Windows Form Applications and other projects.</p></li>
  <li><p>No errors are getting logged on event viewer and I cannot see any other error information apart from what is mentioned above.</p></li>
  </ul>
  
  <p>I searched all over internet but no help. I have already trying un-installing VS2010 using the script at this <a href="http://archive.msdn.microsoft.com/vs2010uninstall/Release/ProjectReleases.aspx?ReleaseId=4321" rel="nofollow">link</a> (provided by MS). But when I re-install VS2010, it still shows me same error. To my surprise, after re-installing VS still shows the previous project list in "Recent Projects". I really doubt if VS is getting uninstalled. </p>
  
  <p>I am totally clueless and any help would be highly appreciated. I am left with no other option but to format my OS if I don't find a solution here :( Please do let me know if any other details are required...</p>
