I think the blog post you referenced is a different case.
I commented on the post, here is my comment:
>From my uderstanding of LINQ in general, I think there is a mistake in the
above code.
A typical ue of the code is:
using (var session = sessionFactory.OpenSession())
{
var nhQueryable = session.Linq< Invoice >();
nhQueryable = nhQueryable.Expand("Items");
var invoice = nhQueryable.Where(i => i.Id == id).First();
}
Note the line:
nhQueryable = nhQueryable.Expand("Items");
This is how IQueryable in general usually works.
Can you try and tell me ?
Not sure about your case though, but from my yunderstanding of LINQ in
general as well, I believe that calling ToList() EXECUTES the LINQ query,
and all the other methods (Skip, First) are LINQ To Objects performed on
the returned List (because it's an IEnumerable). *Can you try without it??*
