It was nice to present at JAXDUG meeting on Wednesday It was a small group that attended this meeting. We had some interesting discussion. I talked on Design Patterns and demonstrated some of the Gang of Four Patterns from the classic design patterns book - Design Patterns: Elements of Reusable Object-Oriented Software (Addison-Wesley Professional Computing Series).

My talk was based on the code examples from the book - Head First Design Patterns (Head First). This book takes a look at various design patterns in a very lively manner with fun examples. I would strongly recommend this book. Although the book is in Java, the fundamental principles of OOAD are the same and explained very nicely.

C# Code Examples 

The above C# code examples are written using Visual Studio 2003 version. In my demo, I showed several class diagrams from this code for various patterns. You can download the updated package from the link below.

The code examples solution contains a project that has unit tests written using Nunit. You’ll need to download NUnit for .NET 2.0.
Thanks to everyone who attended the session. If you have any questions, please feel free to contact me.
