title: How to query against dbo.AspNetUserLogins table (IdentityUserLogin entity)?
body: <p>I am using the standard MVC template with the identity provider in VS 2013.</p>
  
  <p>By extending <code>ApplicationUser:IdentityUser</code>, I am able to access the table <code>AspNetUsers</code> using <code>ApplicationDbContext</code>.  </p>
  
  <p>I now want to query the data in another table, <code>AspNetUserLogins</code>.  How do I reference it without having to create a new database context and a new Entity Data Model to represent this existing table?</p>
