What is the Include(..) method not getting found, on my IObjectSet object, in this Entity Framework code?

Question

Hi folks,

i'm trying to eager load some child entity, and when I try to add the Include() method, i'm getting a compiler error (ie. it can't find it).

er ... can anyone help me out on this one, please?

Answer 1

As far as I can tell, Include() is not a method of IObjectSet, not of any interface it extends:

Include is a member of ObjectQuery (it also returns a ObjectQuery), so you need a ObjectQuery object to start with.
