未找到UserId，在迁移种子中添加用户和角色

Question

我在Migrations / Configuration.cs中有这个种子

    protected override void Seed(xxx.xxx.ApplicationDbContext context)
    {

        var UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(context));
        var RoleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(context));
        string role = "Admin";
        string password = "Password@1234";

        //Create Role Admin if it does not exist
        if (!RoleManager.RoleExists(role))
        {
            var roleresult = RoleManager.Create(new IdentityRole(role));
        }

        //Create Admin users with password=123456
        var admin1 = new ApplicationUser();
        admin1.UserName = "admin1@admin1.com";
        admin1.Email = "admin1@admin1.com";
        admin1.EmailConfirmed = true;
        UserManager.Create(admin1, password);
        UserManager.AddToRole(admin1.Id, role);

        //Create Admin users with password=123456
        var admin2 = new ApplicationUser();
        admin2.UserName = "admin2@admin2.com";
        admin2.Email = "admin2@admin2.com";
        admin2.EmailConfirmed = true;
        UserManager.Create(admin2, password);
        UserManager.AddToRole(admin2.Id, role);

        //Create Admin users with password=123456
        var admin3 = new ApplicationUser();
        admin3.UserName = "admin3@admin3.com";
        admin3.Email = "admin3@admin3.com";
        admin3.EmailConfirmed = true;
        UserManager.Create(admin3, password);
        UserManager.AddToRole(admin3.Id, role);

        context.SaveChanges();           
    }

我收到错误消息“UserId not found”如果我在PM中运行“update-database”或使用复选框“Execute code first migration”进行部署。

修改 我已将用户表重命名为AspNetUsers到Users，请参阅以下IdentityModels中的代码

// Change the name of the table to be Users instead of AspNetUsers
            modelBuilder.Entity<IdentityUser>()
                .ToTable("Users").Property(p => p.Id).HasColumnName("UserID");
            modelBuilder.Entity<ApplicationUser>()
                .ToTable("Users").Property(p => p.Id).HasColumnName("UserID");
