title: Table missing from 'EF Designer from database' .edmx diagram
body: <p>I built a simple ADO.Net MVC project in Visual Studio 2015 by following the tutorial found <a href="http://www.asp.net/mvc/overview/security/create-an-aspnet-mvc-5-web-app-with-email-confirmation-and-password-reset" rel="noreferrer">here</a>. My project works, but I wanted to add more tables to the database and create several foreign key relationships between them and the existing tables. I added an ADO.Net Entity Data Model (Project Properties > Add > New Item > Data > ADO.Net Entity Data Model > EF Designer from Data Model) with all tables selected. I'm using the (localdb)\MSSQLLocalDB that's installed with Visual Studio.</p>
  
  <p>My intention was to create my new tables and FK-relationships in the .edmx diagram, then "Forward Engineer" the modified model back into the database. However, only 5 of the 6 tables created by the ASP.NET MVC template were added to the table. The AspNetUserRoles table was not added. </p>
  
  <p>Can anyone explain why the table was not added and what I should have done to create the new tables and key relationships? I prefer to work in a graphical environment as I am not a DB/SQL expert.</p>
