body: <p>I'm trying to load a web-project in VS2013 and I get the following error.</p>
  
  <p>Full Error: Creation of the virtual directory http:/ /localhost:1234/ failed with the error: The IIS Express applicationHost.config file contains invalid entries and must be corrected.</p>
  
  <p>I've tried different numbers. If I use a portnumber that is configured in IIS I get the error that it's already configured for another webapplication</p>
  
  <p>some of the relevant configuration:</p>
  
  <pre><code>&lt;UseIISExpress&gt;False&lt;/UseIISExpress&gt;
  
  &lt;UseIIS&gt;False&lt;/UseIIS&gt;
  &lt;DevelopmentServerPort&gt;1234&lt;/DevelopmentServerPort&gt;
  &lt;DevelopmentServerVPath&gt;/&lt;/DevelopmentServerVPath&gt;
  &lt;IISUrl&gt;&lt;/IISUrl&gt;
