我不断收到此错误消息“ InvalidOperationException：实体类型'IdentityUserLogin'需要定义主键。”

Question

我通过Identity Framework和Core .Net 2.2不断收到此错误：

InvalidOperationException: The entity type 'IdentityUserLogin'
requires a primary key to be defined.

我查看了其他答案并尝试了建议，但它们仅适用于早期版本。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Identity;
using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore;
using Ca.Models;


namespace Ca.Areas.Identity.Data
{
    public class RMISContext : IdentityDbContext<IdentityUser>
    {
        private object modelBuilder;

        public RMISContext(DbContextOptions<RMISContext> options)
            : base(options)
        {
        }

        protected override void OnModelCreating(ModelBuilder builder)
        {
            base.OnModelCreating(builder);
            // Customize the ASP.NET Identity model and
            override the defaults if needed.
        // For example, you can rename the ASP.NET Identity table
        names and more.
        // Add your customizations after calling base.OnModelCreating
        (builder);

    }
}

}
