If you want to speed up the development of your .NET applications, you're ready for C# design patterns -- elegant, accepted and proven ways to tackle common programming problems. This practical guide offers you a clear introduction to the classic object-oriented design patterns, and explains how to use the latest features of C# 3.0 to code them. C# Design Patterns draws on new C# 3.0 language and .NET 3.5 framework features to implement the 23 foundational patterns known to working developers. You get plenty of case studies that reveal how each pattern is used in practice, and an insightful comparison of patterns and where they would be best used or combined. This well-organized and illustrated book includes: An explanation of design patterns and why they're used, with tables and guidelines to help you choose one pattern over another Illustrated coverage of each classic Creational, Structural, and Behavioral design pattern, including its representation in UML and the roles of its various players C# 3.0 features introduced by example and summarized in sidebars for easy reference Examples of each pattern at work in a real .NET 3.5 program available for download from O'Reilly and the author's companion web site Quizzes and exercises to test your understanding of the material. With C# 3.0 Design Patterns, you learn to make code correct, extensible and efficient to save time up front and eliminate problems later. If your business relies on efficient application development and quality code, you need C# Design Patterns.

This is a good rehash of the Gang of Four patterns, reworked in C# 3.0. The book's fairly concise and most patterns are clearly laid out with a simplistic example to demonstrate the basics of the patterns followed by a more detailed example in a semi-real world implementation.

The articles are nicely done, there are a good set of exercises about each pattern, and there are some good comparisons between similar patterns. As an example, there's a bit comparing the Builder and Abstract Factory which details that a Builder is concerned with how things are built while an Abstract Factory is concerned with what is built.

A couple things bothered me in the book, namely the lack of a clear overall summary of patterns, and an annoying batch of sidebars on fairly basic concepts. While each pattern has a summary of when you would use it, you're forced to dig through the entire book looking at each pattern trying to figure out if it will solve a problem for you. A consolidated list of the uses of each pattern at the start or end of the book would have been a great help. Regarding the sidebars: do I need a patterns book to lay out fundamental concepts like accessibility modifiers or indexers? These detract from the book's main purpose, which isn't to teach C# 3.0, but show how patterns are done in C# 3.0. Sidebars specific to a pattern's C# 3.0 intricacies are OK, but the fundamentals should have been left out.
