title: How to use ASP.NET Identity 3.0 without Entity Framework
body: <p>All examples I've seen by now for ASP.NET Identity 3.0 use Entity Framework to store user-related data.</p>
  
  <p>Are there any example which does not use Entity Framework and where <code>ApplicationUser</code> class is not derived from <code>Microsoft.AspNet.Identity.EntityFramework.IdentityUser</code>?</p>
  
  <p>In ASP.NET Identity 2.x it was needed to implement <code>IUser</code> interface. It seems there is not such interface now - so we're not sure how to define <code>User</code> class correctly. There is almost no documentation on this subject.</p>
  
  <p>Second problem is with <code>AddIdentity</code> call in <code>Startup.ConfigureServices</code>. It's pretty tied to the particular classes from <code>Microsoft.AspNet.Identity.EntityFramework</code> namespace and it's unclear how to register identity services without those classes.</p>
