ef升级到6.1后，left outer join 变成 inner join 怎么办？

[jeanso]

之前4.1 ，杠杠的，升级成6.1 left outer 失效，变成inner join
public class CorpMember
{
public int? CMCID { get; set; }

public virtual CorpMemberCategory category{ get; set; }
}


Dbcontext：

modelBuilder.Entity<CorpMemberCategory>().HasMany(a => a.corpmembers).WithRequired(p => p.category);
modelBuilder.Entity<CorpMember>().HasRequired(a => a.category).WithMany().HasForeignKey(a => a.CMCID);

使用可为空的外键即可实现left 效果，升级成6.1 直接变成inner join

有没哪位大侠遇到过，怎么解决的啊？

4.1没问题，

from e in mySet.Where(specification.SatisfiedBy())
join cate in base.DataContext.CorpMemberCategory on e.CMCID equals cate.CMCID into catelist
from cc in catelist.DefaultIfEmpty()
或 直接用导航属性
from e in mySet.Where(specification.SatisfiedBy())
select new { e.Address, e.category.CateName
都没问题


6.1就出问题了，该怎么设置呢？

谢谢

不懂帮顶 不过你的left outer join 是怎么变成 inner join的？
