我有休闲的模特

namespace Prometheus.Models
{
    [Table("People")]
    public class Person : IPerson
    {
        [Key]
        [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
        public int Id { get; set; }
        public string FirstName { get; set; }

        public string LastName { get; set; }

        public string Name
        {
            get
            {
                return FirstName + " " + LastName;
            }
            set{}
        }

        public string Email { get; set; }
        public DateTime? LastModified { get; set; }
    }
}

一个继承它的人

namespace Prometheus.Models
{
    [Table("UserProfile")]
    public class UserProfile : Person
    {
        public string UserName { get; set; }
        public string CNP { get; set; }
        public virtual Faculty Faculty { get; set; }
        public bool? IsUSAMV { get; set; }
        public virtual ICollection<Result> Results { get; set; }
        public virtual ICollection<Project> Projects { get; set; }
    }
}

和种子的方法

private void AddUser(string user, string password,
    SimpleMembershipProvider membership)
{
    if (membership.GetUser(user, false) == null)
    {
        WebSecurity.CreateUserAndAccount(user, password, new
        {
            CNP = "1890531111111",
            IsUSAMV = true,
        });
    }
}

当我尝试在没有UserProfile扩展Person的情况下运行种子方法时，一切都很好，但是当它扩展时，我一直收到错误提示。

The INSERT statement conflicted with the FOREIGN KEY constraint "FK_dbo.UserProfile_dbo.People_Id". The conflict occurred in database "PrometheusDb", table "dbo.People", column 'Id'.
The statement has been terminated.

任何帮助将不胜感激谢谢。

我尝试将我的功能更新为

private void AddUser(string firstName,string lastName, string password,
    SimpleMembershipProvider membership)
{
    var user = firstName + "." + lastName;
    if (membership.GetUser(user, false) == null)
    {
        var profile = new UserProfile()
        {
            Email = "test@email.com",
            FirstName = firstName,
            LastName = lastName
        };
        _context.Users.Add(profile);
        _context.SaveChanges();
        WebSecurity.CreateAccount(user, password);
    }
}

但是现在我得到：- 更新条目时发生错误。
