The Unit of Work Pattern - Part Deux

Last week’s post, Implementing a persistence ignorant Unit of Work framework (if you haven’t read this post yet I would encourage you to do so as this post builds on the previous post), showed how to implement a foundation for the Unit of Work pattern that can be used to implement specific Unit of Work components for any type of persistence framework. In this post I’m going to enhance on the existing foundation to add another level to the Unit of Work, something I call the Unit of Work Scope that allows cascading unit of work scopes and transaction sharing.
