我正在尝试在ApplicationUser和Reserve之间创建多对多关系。
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; }
}
但我无法添加迁移
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.
无论如何,相同的关系适用于其他实体但不适用于ApplicationUser。
我可以使用ApplicationUser多对多吗?
答案 0 :(得分:1)
我在ef核心中找到了以下内容: 尚不支持没有实体类来表示连接表的多对多关系。 所以我的问题已经结束了。
