Note: This project will be superceded in NH3.0 by Query-Over

see: http://nhforge.org/blogs/nhibernate/archive/2009/12/17/queryover-in-nh-3-0.aspx

A project that provides extension methods for the NHibernate ICriteria interface to allow use of typesafe lambda expressions.

e.g.,

    .Add(Expression.Eq("Name", "Smith"))

becomes

    .Add<Person>(p => p.Name == "Smith")
