C# Class UCDArch.Data.NHibernate.NHibernateSessionManager

Handles creation and management of sessions and transactions. It is a singleton because building the initial session factory is very expensive. Inspiration for this class came from Chapter 8 of Hibernate in Action by Bauer and King. Although it is a sealed singleton you can use TypeMock (http://www.typemock.com) for more flexible testing.
