title: ASP.NET MVC app restarts itself
body: <p>We are encountering an issue where our ASP.NET MVC app is restarting for an unknown reason.  The cause of the shut down is </p>
  
  <p>"A subdirectory in the Bin application directory was changed or renamed."  </p>
  
  <p>The file in question turned out to be C:\Users\Jason\AppData\Local\Temp\Temporary ASP.NET Files\root\f691a68c\a1593a1e\hash\hash.web.  </p>
  
  <p>Something noteworthy is that we are starting up a NServiceBus client in Application_Start and if we comment out that line, our web app doesn't restart itself.  The the questions are: 1) What does hash.web do and 2) Is this issue NServiceBus related?</p>
