Howdy,<BR>I was curious and would like to see some discussion raised about .Net Class Diagrams and Architecture. Does anyone out there have any good links or suggestions about how to relate your Presentation Level or GUI with your Business Model, specifically info on facades, mvc, and controllers. I am in the process of designing a Web App with a Admin Account and would like understand how to best facilitate the richness and oop that .Net has to Offer. I am eagerly awaiting your responses and very much obliged.<BR>Frank
