FluentNHibernate.Mapping.Builders namespace

I want to try a class from the FluentNHibernate.Mapping.Builders namespace called CompositeElementBuilder but开发者_如何学运维 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,

Matthew

No it should be in that assembly. I just looked through the object browser and I saw it.
Did you remember your: using FluentNHibernate.Mapping.Builders;

Edit:

I am using version 1.1.0.0. This does not appear to be in version 1.1.0.685 (Current on website).
