title: System.InvalidOperationException: Failed to map the path '/'
body: <p>I have a web application that runs in visual studio 2010.</p>
  
  <p>For tests purposes I configured a site on IIS for the same physical path used in visual studio.</p>
  
  <p>After this configuration, if i start the project from visual studio i get the following error</p>
  
  <blockquote>
    <p>System.InvalidOperationException: Failed to map the path '/'.</p>
  </blockquote>
  
  <p>I've tried everything I could think of, even deleting the website, but the problem persists...</p>
  
  <p>Any ideias?</p>
