FluentNHibernate.Mapping.Builders namespace
I want to try a class from the FluentNHibernate.Mapping.Builders namespace called CompositeElementBuilder but after setting a reference to the FluentNHibernate assembly I can can't get this namespace. Is there a separate assembly that contains the FluentNHibernate.Mapping.Builders namespace?

Thanks,
