title: IdentityConfig is missing in MVC 5
body: <p>I am migrating my project to MVC 5 and I've just installed Visual Studio 2013 RC. As far as I can see there must be a file named <em>IdentityConfig.cs</em> in the <em>App_Start</em> directory, but even if I create a new project, that file is missing. I am thinking that maybe it could be about version of Visual Studio that I am using. Is there anyway to solve this problem?</p>
  
  <p>Also, I can't add Roles or Membership Providers to <em>web.config</em>. How can I do this with IdentityConfig?</p>
