title: .vs\config\applicationhost.config in source control
body: <p>Visual Studio 2015 adds a file named <code>.vs\config\applicationhost.config</code>
   to the root of a solution when an ASP.NET Web application project is created.</p>
  
  <p>Should this file be checked in to source control or should it be ignored (so that each user will have their own local copy)?</p>
