带有EF6的'on子句'中的MySQL Unknown列'Extent1.ID'

Question

我有以下类结构

awk

我需要获取问题详情，因为我使用

public class Question
{
    public long ID { get; set; }
    public string Content { get; set; }
    public DateTime On { get; set; }
    public Member Member { get; set; }
    public List<Answer> Answers { get; set; }
}
public class Answer
{
    public long ID { get; set; }
    public string Content { get; set; }
    public DateTime On { get; set; }
    public Member Member { get; set; }
    public List<Star> Stars { get; set; }
    public List<Reply> Replys { get; set; }
}
public class Reply
{
    public long ID { get; set; }
    public string Content { get; set; }
    public DateTime On { get; set; }
    public Member Member { get; set; }
}
public class Star
{
    public long ID { get; set; }
    public Member Member { get; set; }
}

但是这句话给了我一个例外

'on clause'

中的未知列'Extent1.ID'

如果我从任何Include中移除一个包含或删除成员，它就可以正常工作。

我遇到了类似的MySQL EF 6问题，该问题已发布here。使用的MySQL版本是MySQL 6.9.7.0。
