I am following this tutorial to seed ASP.NET Identity user and roles in .NET Core 3.1

But when I add migration, I got exception

PM> add-migration seed -context ApplicationDbContext Build started... Build succeeded. System.InvalidOperationException: The entity type 'IdentityUserLogin' requires a primary key to be defined.

This is my code:

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
    {
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
        {

        }
        protected override void OnModelCreating(ModelBuilder builder)
        {
            //base.OnModelCreating(builder);
            string ADMIN_ID = "02174cf0–9412–4cfe-afbf-59f706d72cf6";
            string ROLE_ID = "341743f0-asd2–42de-afbf-59kmkkmk72cf6";

            //seed admin role
            builder.Entity<IdentityRole>().HasData(new IdentityRole
            {
                Name = "SuperAdmin",
                NormalizedName = "SuperAdmin",
                Id = ROLE_ID,
                ConcurrencyStamp = ROLE_ID
            });

            //create user
            var appUser = new ApplicationUser
            {
                Id = ADMIN_ID,
                Email = "[email protected]",
                EmailConfirmed = true,                
                UserName = "[email protected]"
            };

            //set user password
            PasswordHasher<ApplicationUser> ph = new PasswordHasher<ApplicationUser>();
            appUser.PasswordHash = ph.HashPassword(appUser, "mypassword_?");

            //seed user
            builder.Entity<ApplicationUser>().HasData(appUser);

            //set user role to admin
            builder.Entity<IdentityUserRole<string>>().HasData(new IdentityUserRole<string>
            {
                RoleId = ROLE_ID,
                UserId = ADMIN_ID
            });
        }
    }
