Can't add controller of model that inherits from other class

Question

I'm using Entity Framework and MVC3, and my problem is that I can't scaffold Controllers if the Model inherits from another Class. Example: ``` public class Person { public int Id { get; set; } public string Name { get; set; } } public class User : Person { public string Email { get; set; } public string Password { get; set; } } public class Context : DbContext { public DbSet PersonSet { get; set; } } ``` When I try to Add the Controller `User` using template `Controller with read/write actions and views, using Entity Framework` I get this error: 'User' is not part of the specified 'Context' class, and the 'Context' class could not be modifed to add a 'DbSet' property to it. (For example, the 'Context' class might be in a compiled assembly.) I could add `public DbSet UserSet { get; set; }` to the `Context` but I don't think it is the right aproach.

Accepted Answer

At the moment your `User` is not persisted type because context doesn't know that type so you cannot use scaffolding of persisted entity types to create controller for `User` type. If you want to store `User` and its properties in database add this to your context:

```
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    modelBuilder.Entity<User>();
}
```

If you don't want to persist `User` to database you cannot use scaffolding for controller creation.
