Custom Collections with NHibernate, Part II: The Basics

In part one of this three part series, I offered what we’d ideally like when using NHibernate, or any ORM for that matter, with custom collections in the domain layer. To reiterate, the ORM should have as little impact as possible on how custom collections within the domain are structured and how relationships between classes are declared. At the very least, there should be no references to the ORM, or ORM-supporting assemblies from the domain, whatsoever. The discussed solution achieves these goals.
