I just need Parent objects. In SQL, this is simple:
select distinct * from parent join child on child.ParentID = Parent.ID where child.playssoccer = true;
In Entity Framework 6, this seems like splitting the atom to me.
I need new p => parent where parents.children.playssoccer = true .
How do I get soccer parents out of a similar EF6 DBContext?
from p in context.Parents where p.Children.Any(c => c.PlaySoccer == true) select p
This is assuming you want parents who have at least one child that plays soccer.
If you have navigation properties you can do something like
Parents.Where(p => p.child.playsoccer)
