.Net Patterns

When I was studying Software Engineering I look at the website data & object factory. There you can find the Gang of Four (GoF) typical patterns translated to C#. You know, Factories, Sigletones, Facades... I found that this patterns have a heavy Java look and feel, and pretty boring, being a big hole for a formal definition of the patterns being used in the .Net world taking profit of the .Net languages improvements, as generics, delegates...

One example of pattern that fits in this hole is the Scope pattern.
