title: IIS Express stops after saving *.cs or *.cshtml file in Visual Studio 2015
body: <p>Im testing new <code>ASP.NET 5</code> web template in Visual Studio 2015 Ultimate CTP 5.
  (14.0.22412.0 DP)</p>
  
  <p>My problem is, that when i run application, each time i press save on any of <code>.cs</code> or <code>.cshtml</code>files, server stops. No warnings or error dialogs appear.</p>
  
  <p>I can reproduce error using empty starter projects:</p>
  
  <pre><code>file-&gt;new project-&gt; ASP.NET Web Application -&gt; ("ASP.NET 5 Empty" and same with "ASP.NET 5 Starter Web")
  </code></pre>
  
  <p>After trying to locate the source of problem, i found this in output window:</p>
  
  <pre><code>iisexpress.exe Information: 0 : Deleted -&gt; c:\users\admin\documents\visual studio 2015\Projects\WebApplication4\src\WebApplication4\Startup.cs
  iisexpress.exe Information: 0 : [ApplicationShutdown]: Scheduling shutdown request for debugger detach.
  iisexpress.exe Information: 0 : c:\users\admin\documents\visual studio 2015\Projects\WebApplication4\src\WebApplication4\0sc2sxcq.1a1~ -&gt; c:\users\admin\documents\visual studio 2015\Projects\WebApplication4\src\WebApplication4\Startup.cs
  iisexpress.exe Information: 0 : [ApplicationShutdown]: Requesting shutdown.
  The program '[7760] iisexpress.exe: Program Trace' has exited with code 0 (0x0).
  The program '[7760] iisexpress.exe' has exited with code -1 (0xffffffff).
  The program '[7348] iexplore.exe' has exited with code -1 (0xffffffff).
  </code></pre>
  
  <p>So it seems that saving file deletes it, and deleting file triggers shutdown.
  I don't think its intended that way.</p>
  
  <p>Using View In Browser instead debugging works (but i want to use debug)</p>
  
  <p>What i tried:</p>
  
  <ul>
  <li>Reinstalling Visual Studio</li>
  <li>Disabling Web Essentials/Resharper</li>
  <li>Running all available Target KRE versions</li>
  <li>Switching to Release </li>
  </ul>
  
  <p>I would format my PC, but this seems a bit drastic.</p>
  
  <p>I am using Windows 8.1 Pro</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>Problem persist in VS 2015 CTP <strong>6</strong> </p>
  
  <p>("Microsoft.AspNet.Server.IIS" versions <strong>1.0.0-beta2</strong> and <strong>1.0.0-beta3</strong>)</p>
