the beta version of nh include ToFuture and ToFutureValue for Linq
My question is.... How can i do the example below in Linq:
var persons = s.CreateQuery("from Person")
.SetMaxResults(10)
.Future<Person>();
var personCount = s.CreateQuery("select count(*) from
Person")
.FutureValue<long>();
Thanks in advance
