Question

I have a query below, but I want to perform an Include() to eager load properties. Actions has a navigation property, User (Action.User)

1) My basic query:

Answer 1

Doing the basic query mentioned in your posted question you won't be able to see the User properties unless you return an anonymous type as following:

from a in Actions
join u in Users on a.UserId equals u.UserId
select new
{
   actionUserId = a.UserId
   .
   .
   .
   userProperty1 = u.UserId
};

However to use the Include method on the ObjectContext you could use the following:

Make sure you have LazyLoading off by using the following line:

entities.ContextOptions.LazyLoadingEnabled = false;

Then proceed by

var bar = entities.Actions.Include("User");
var foo = (from a in bar
           select a);
