Asp.net mvc Insert语句与实体框架一对一关系的外键约束fk_dbo冲突

我有三个实体类。我试图做的是将数据插入到

User

表中，同时将数据插入到名为

Company

的表中。和

所有者

以下是我的代码：（如标题所述，我遇到了插入错误）

---

向我们展示真正执行插入的代码！这意味着：显示

\u userService.Insert（usr）中的内容

@GertArnold对不起，我清除了数据库并再次创建，它解决了问题，似乎是一个不需要的FK asignto Db，然后留在那里。这就是问题所在谢谢大家。

public class User : BaseEntity
{
        [Key]
        public int Id { get; set; }

        public virtual Company.Company Company { get; set; }
          public virtual  Owner.Owner Owner { get; set; }
        public string Username { get; set; }
        ...........
}

public class Company : BaseEntity
{
        [Key, ForeignKey("User")]
        public int Id { get; set; }

        public string Name { get; set; }  
        public virtual User User { get; set; }
        public string Explanation { get; set;            
        ...........
}



public class Owner:BaseEntity
    {
        [Key, ForeignKey("User")]

        public int Id { get; set; }

        public string NameSurname { get; set; }
        public string Email { get; set; }
        public string CellPhone { get; set; }
       ...........
        public virtual User User { get; set; }
    }


        User usr=new User {  
      usr.NameSureName = user.NameSureName;
        usr.Email = user.Email;
         ...........
               };

        var company = new Company
        {

            CompanyMemberShipType = CompanyMemberShipType.Free,


        };
        var owner = new Owner
        {

            CellPhone = user.CellPhone,
            Email = user.Email,
            NameSurname = user.NameSureName
        };
        usr.Company = company;
        usr.Owner = owner;
       var userresult = _userService.Insert(usr);
