Question

我已经开始学习.NET CORE，并且我想实现基本的用户身份验证和授权。我尝试创建基于Onion Architecture的基础应用程序，因此创建了对其他项目的引用。现在，它看起来像这样：

Project.Core（我的数据库带有IdentityDbContext）-> Project.Data-> Project.Services-> Project.Ui（在这里，我尝试了在此处实施Auth系统）

我在编译过程中没有收到错误消息，但是在运行整个应用程序之后却收到了一条巨大的错误消息。至少有5个例外。

我应该实施其他服务吗？如果是，在哪里？用IDesignTimeDbContextFactory创建这样的数据库有效吗？

请在下面也找到代码示例。

        [MaxLength(200)]  
        public string Nick {get; protected set;}

        [Required]  
        [MaxLength(200)]  
        public String Name { get; set; }  

        [Required]  
        [MaxLength(250)]  
        public String Surname { get; set; } 

        [Required]   
        [MaxLength(250)]  
        public string Password {get; protected set;}
        public User(string nick, string name, string surname, string email, string password)
        {
            Nick = nick;
            Name = name;
            Surname = surname;
