我想从类模型图到ApplicationUser之间建立关系。应用程序用户可能与图无关,或与图完全单一的关系。图总是和ApplicationUser有关系。ASP.Net与标识模型的一对一或零关系
我试图做到这一点在我的代码:在包管理器运行add-migration Figure
时
图模型
public class Figure
{
[Key]
public string FigureId { get; set; }
public string Description { get; set; }
public string UserId { get; set; }
[ForeignKey("UserId")]
public virtual ApplicationUser User { get; set; }
}
AplicationUser模式
public class ApplicationUser : IdentityUser
{
[Required]
public string FirstName { get; set; }
[Required]
public string LastName { get; set; }
[Required]
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
public DateTime BirthDate { get; set; }
public string Occupation { get; set; }
public string Location { get; set; }
public virtual Figure Figure { get; set; }
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
return userIdentity;
}
}
然后我得到这个控制台:
System.InvalidOperationException: Multiple object sets per type are not supported. The object sets 'ApplicationUsers' and 'Users' can both contain instances of type 'Lacivi.Models.ApplicationUser'.

最后一行显示为红色。我想知道这肯定是问题,但我不明白。
我没有,除了那些财产,'名字添加任何东西''LastName'''BirthDate'等 –
我在说你的dbcobtext类。您没有粘贴这部分代码。你可以在这里添加它吗? – Tacud
