Hello Ben Friedman,
We have made improvements in Linq regarding the types of queries that you reported. There are some old warnings left as the one you are getting. Therefore, the warning you are getting is an 'obsolete' one itself. We have removed the obsolete warnings so you will not see those in the next versions of OpenAccess. The query you are executing is pushed properly to the server. Before supporting such queries, the form of your query would have been like:
|var query = scope.Extent<Story>().Where(a=>a.Publish).Count();
If you write it in this form, the warning you are getting should not be there anymore.
