.net MapInheritedProperties（）未映射继承的外键属性

这是我的实体类：

public abstract class Entity: IEntity
{
    public Guid? Id { get; set; }    
    public bool IsDead { get; set; }
    public DateTime Created { get; set; }
    public DateTime Modified { get; set; }
    public ICollection<EntityAccess> AccessList { get; set; }
    public ICollection<Message> Discussion { get; set; }
    public User Owner { get; set; }
}

EF创建数据库后，发生了一些非常奇怪的事情。从实体继承的属性确实映射到每个表，除了所有者属性。与其他继承属性不同，所有者未映射。怎么解释呢

附加信息：我的实体是简单的POCO对象，没有注释，没有构造函数，什么都没有。例如，以下是用户实体：

public class User : RuntimeEntity
{
    public string Email { get; set; }
    public ICollection<UserGroup> Groups { get; set; }
    public byte[] Password { get; set; }
    public ICollection<Membership> Memberships { get; set; }
}

公共类用户：RuntimeEntity
{
公共字符串电子邮件{get；set；}
公共ICollection组{get；set；}
公共字节[]密码{get；set；}
公共ICollection成员身份{get；set；}
}
