If you're in the San Diego area, I'll be speaking at the San Diego .NET User Group tomorrow night (March 27th). Details are available here: San Diego .NET User Group.
The topic is "Learn the Lingo: Design Patterns". We'll be taking a look at what patterns are and why we should become familiar with them. In addition to looking at several Gang of Four patterns, I'll show some commonly used patterns like the Repository, Inversion of Control (IoC), and Model-View-ViewModel (MVVM). Lots of fun in store; hope to see you there.
