title: How to inherit from IdentityUser in entity framework designer
body: <p>I have an asp.net mvc project that uses asp.net Identity to authenticate users. The database has been designed in entity framework designer.</p>
  
  <p>There is a table named "Farmers" and I want to allow each farmer to login to the application. As I know in order to achieve this, the farmer must inherit from IdentityUser, but how can I do this in entity framework designer?</p>
