The return from the second function needs to be:

return query.OrderByDescending(conference => conference.EndDate).First();

query.OrderByDescending(conference => conference.EndDate);
return query.First();

Lets see how that goes

The above doen’t work as expected. It returns 2004 – from conferencerepositorytester.

Actually needs the following:

public Conference GetMostRecentConference(DateTime date)
{
ISession session = getSession();
var query = from conference in session.Linq()
where conference.EndDate conference.EndDate).First();
}

This returns 2005. Subtle difference that has burnt me before.
