我正嘗試在ApplicationUser和Reserve之間創建一個多對多的關係。ApplicationUser多對多EF核心
public class ApplicationUser : IdentityUser
{
public ApplicationUser()
{
this.Reserves = new HashSet<Reserve>();
}
public bool IsProfessional { get; set; }
public virtual ICollection<Reserve> Reserves { get; set; }
}
public class Reserve
{
public Reserve()
{
this.Usuarios = new HashSet<ApplicationUser>();
}
public int ID { get; set; }
public string Begin { get; set; }
public string End { get; set; }
public string Date { get; set; }
public string Status { get; set; } //free , reserved, confirmed, canceled
public DateTime LastUpdate { get; set; }
public virtual ICollection<ApplicationUser> Usuarios { get; set; }
}
,但我不能添加遷移
PM> Add-Migration user-reserve-relationship
Unable to determine the relationship represented by navigation property 'ApplicationUser.Reserves' of type 'ICollection<Reserve>'. Either manually configure the relationship, or ignore this property from the model.
不管怎樣,同樣的關係能很好地其他實體,但不是ApplicationUser。
我可以使用ApplicationUser multi-to-many嗎?
