title: Cannot run web application on Windows 10 using IIS Express
body: <p>I am developing a web application using ASP.NET MVC (a rather simple application, having just a single controller and a few routes; there´s nothing fancy in it). In the beginning I used Visual Studio 2013 and Windows 8/8.1. A couple of days ago I switched to Windows 10 and I am having trouble to run the application on my local development machine (I have both Visual Studio 2013 and 2015 installed, but I continue using Visual Studio 2013 for this project).</p>
  
  <p>When I start a new instance for debugging, IIS Express starts, Visual Studio launches the selected browser (which is Edge by default), but the request to the site never returns a valid response.</p>
  
  <p>I can see in the system tray, that the application seems to be running fine. I also checked with Fiddler; and Fiddler shows me that the browser´s request never gets a response from the local server. Can this be an issue with the firewall?</p>
  
  <p><strong>Update</strong></p>
  
  <p>I think it has nothing to do with the Edge-browser nor with the <code>localhost loopback</code> setting (this setting has been enabled via <code>about:flags</code> page). Furthermore, I experience this problem under the final version of Windows 10.</p>
