Custom Identity User MVC 5 generates two user tables

Question

I'm trying to customize my IdentityUser to generate a primary key as integer and change the table names. The thing is: the primary key is generated correctly and all standard tables are created correctly by Migration with the new names, except by the User one. When I apply the Add-Migration Comand it returns me two "user tables".

Here is my code.

My custom Identity classes

public class User : IdentityUser<int, CustomUserLogin, CustomUserRole, CustomUserClaim>
{
}
public class CustomUserRole : IdentityUserRole<int> { }
public class CustomUserClaim : IdentityUserClaim<int> { }
public class CustomUserLogin : IdentityUserLogin<int> { }

public class CustomRole : IdentityRole<int, CustomUserRole>
{
    public CustomRole() { }
    public CustomRole(string name) { Name = name; }
}

My ApplicationDbContext

public class ApplicationDbContext : IdentityDbContext<ApplicationUser, CustomRole, int, CustomUserLogin, CustomUserRole, CustomUserClaim>
{
    public ApplicationDbContext() : base("CONNSTRING") { }


    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Entity<User>().ToTable("Users", "dbo");
        modelBuilder.Entity<CustomRole>().ToTable("Role","dbo");
        modelBuilder.Entity<CustomUserRole>().ToTable("UserRole", "dbo");
        modelBuilder.Entity<CustomUserLogin>().ToTable("UserLogin", "dbo");
        modelBuilder.Entity<CustomUserClaim>().ToTable("UserClaims", "dbo");


    }
}

And the script generated by EF, which you can see generates me two "User tables" : the standard one "AspNetUsers" and my custom one "Users".

            DropTable("dbo.UserRole");
            DropTable("dbo.Role");
        }
    }

Additional information: The application uses the "AspNetUsers" table as the principal one.

Thankful for any help.

I think you will have to map the IdentityUser to your new user table like this in your OnModelCreating method.

modelBuilder.Entity<IdentityUser>()
                        .ToTable("Users", "dbo").Property(p => p.Id).HasColumnName("UserId");
