If you subscribe to his theory, how would you implement this in C#?
If you don’t subscribe to his theory, and wish to debate the topic, please do it outside of this post (I suggest her: Feel free the comment here with regard to the actual pattern: — https://plus.google.com/105106301233937725736/posts/QvhKbB3y7F2 .)
This question is about how to best implement that pattern in C#. Acceptable answer describes a set of rules to use this pattern from C#
