Fluent NHibernate
Mapping Patterns Collection With Backing Field

This is part of the Mapping Patterns collection.

This article addresses the following situation:

• You have an entity that has a collection of related entities
• That collection is only modified via mutator methods (i.e. AddFoo() or RemoveFoo())
• The collection is a private/protected field in your entity class definition and needs to be mapped with NHibernate.

The solution for this situation is covered in the Standard Mapping Relationships article
