title: Error: The type or namespace name 'ApplicationUser' could not be found in Visual Studio 2013
body: <p>I am following the "RESTful WCF Service" tutorial. But when I built my application I get this error:</p>
  
  <blockquote>
    <p>The type or namespace name 'ApplicationUser' could not be found (are you missing a using directive or an assembly reference?) 
    c:\users\basma\documents\visual studio 2013\Projects\OnlineStore2\OnlineStore2_Client\App_Start\IdentityConfig.cs </p>
  </blockquote>
  
  <p>I've searched and many answers where talking about "Microsoft ASP.NET Identity.owin" but I added this reference but still get this error</p>
