Question

I have an Entity A which is related to entity B on a 1:M relationship.
B is related to C in a 1:M relationship.

A –> B
B –> C

How do I go about including the collection of C when I include B on A?

I have this:

return (from d in _contextProvider.GetContext<SomeContext>().GetObjectQuery<A>().Include("B")
                select d).SingleOrDefault();

I tried this but throws error because it thinks C is related to A and can’t find the relationship.

return (from d in _contextProvider.GetContext<SomeContext>().GetObjectQuery<A>   ().Include("B").Include("C")
                select d).SingleOrDefault();

Answer 1

Try

return (from d in _contextProvider.GetContext<SomeContext>().GetObjectQuery<A>().Include("B").Include("B.C")
select d).SingleOrDefault();
