OK, well I will look into that. The idea is to get something friction- less for simple scenarios where you are doing,for example, paging and sorting on a UI, and want to push those queries through to NH in an easy manner. We were doing NH linq queries, combined with dynamic queryable (for sorting based off the string name of a field). I wanted to try to use futures to wrap the query for the data and the query for the total records into one DB call.That was trivial with criteria, but not so much with linq.
I will have to look into queryover.
