C# 如何将Employees导航属性添加到已具有Manager导航属性的ASP.NET Identity ApplicationUser？

我目前拥有

ApplicationUser

实体，该实体从身份框架扩展了

IdentityUser

[Table("User")]
public class ApplicationUser : IdentityUser<string, IdentityUserLogin, ApplicationUserRole, IdentityUserClaim>
{
    [Column("CreatedDate"), DataType("datetime2")]
    public DateTime? CreatedOn { get; set; }
    [Column("CreatedBy")]
    public string CreatedBy { get; set; }

    [Column("ModifiedDate"), DataType("datetime2")]
    public DateTime? ModifiedOn { get; set; }
    [Column("ModifiedBy")]
    public string ModifiedBy { get; set; }

    [Column("LastLoginDate"), DataType("datetime2")]
    public DateTime? LastLoginOn { get; set; }

    [Column("TimeZoneID"), ForeignKey("TimeZone")]
    public string TimeZoneId { get; set; }
    [Column("RegionID"), ForeignKey("Region")]
    public string RegionId { get; set; }
    [Column("ManagerID"), ForeignKey("Manager")]
    public string ManagerId { get; set; }

    public virtual TimeZone TimeZone { get; set; }
    public virtual Region Region { get; set; }
    public virtual ApplicationUser Manager { get; set; }

    public virtual ICollection<Appointment> Appointments { get; set; }
    public virtual ICollection<OnCallGroup> OnCallGroups { get; set; }


    public ApplicationUser()
    {
        Id = Guid.NewGuid().ToString();
        Appointments = new HashSet<Appointment>();
        OnCallGroups = new HashSet<OnCallGroup>();
    }

    public ApplicationUser(string userName)
        : this(userName, DateTime.UtcNow)
    {
    }

    public ApplicationUser(string userName, DateTime createdOn)
        : this()
    {
        UserName = userName;
        CreatedOn = createdOn;
        Email = userName;
        EmailConfirmed = true;
    }

    private ClaimsIdentity GenerateUserIdentity(ApplicationUserManager manager)
    {
        var userIdentity = manager.CreateIdentity(this, DefaultAuthenticationTypes.ApplicationCookie);
        return userIdentity;
    }

    public Task<ClaimsIdentity> GenerateUserIdentityAsync(ApplicationUserManager manager)
    {
        return Task.FromResult(GenerateUserIdentity(manager));
    }
}

我想添加另一个导航属性，以便容纳属于某些用户的技术人员或员工（例如管理角色），这是一个好主意吗？我怎样才能继续

仅添加以下行即可添加另一个导航属性：

public virtual ICollection<ApplicationUser> Employees { get; set; }

公共虚拟ICollection雇员{get；set；}

你试过了吗？你试过了吗？

public virtual ICollection<ApplicationUser> Employees { get; set; }
