在.NET Core 3.1中为ASP.NET标识用户和角色设定种子

Question

我将按照本教程在.NET Core 3.1 中为ASP.NET Identity用户和角色设定种子

但当我添加迁移时，我得到了异常

PM>添加迁移种子-context ApplicationDbContext Build已启动。。。生成成功。System.InvalidOperationException：实体类型"IdentityUserLogin"需要定义主键。如果您打算使用无键实体类型调用"HasNoKey(("。在Microsoft.EntityFrameworkCore.Infrastructure.ModelValidator.ValideNonNullPrimaryKeys(IModel型号，IDiagnosticsLogger1

这是我的代码：

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 = "[e-mail]",
EmailConfirmed = true,                
UserName = "[e-mail]"
};
//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
});
}
}
