User in Entity type MVC5 EF6

Question

I have created a class in MVC5, where I want a primary owner of the content and then I want to have some editors for the content:

public class Content {     public int ID { get; set; }     public IdentityUser Owner { get; set; }     public ICollection<IdentityUser> Editors { get; set; }     public string Title{ get; set; }     public string Body { get; set; } } 

In the database context I have the following code:

protected override void OnModelCreating(DbModelBuilder modelBuilder) {     base.OnModelCreating(modelBuilder);      modelBuilder.Entity<Content>()         .HasOptional(c => c.Editors)         .WithRequired()         .WillCascadeOnDelete();      modelBuilder.Entity<Content>()         .HasRequired(c => c.Owner)         .WithOptional()         .WillCascadeOnDelete(); } 

I would expect Microsoft to have implemented the IdentityUser object in such a way, that it can be used in other entity types, so I am probably doing something wrong, because when I try to make a controller for the Content entity type, I get the following error:

EntityType 'IdentityUserLogin' has no key defined EntityType 'IdentityUserRole' has no key defined EntityType: EntitySet 'IdentityUserLogins' is based on type 'IdentityUserLogin' that has no key defined EntityType: EntitySet 'IdentityUserRoles' is based on type 'IdentityUserRole' that has no key defined 

I have also tried to add the following code to the ApplicationDbContext as described in this question Map tables using fluent api in asp.net MVC5 EF6?:

protected override void OnModelCreating(DbModelBuilder modelBuilder) {     base.OnModelCreating(modelBuilder);     modelBuilder.Entity<IdentityUserLogin>().HasKey<string>(l => l.UserId);     modelBuilder.Entity<IdentityRole>().HasKey<string>(r => r.Id);     modelBuilder.Entity<IdentityUserRole>().HasKey(r => new { r.RoleId, r.UserId }); } 

I must be doing something wrong. Please tell me how I can handle users in my Content EntityType.

I had the same problem and I found that I had not called

 base.OnModelCreating(modelBuilder); 

in my DbModel
