I took on this book at the same time that I was hired at Microsoft. Completing the book while navigating the requirements of a new job was, umm, not an experience that I ever want to repeat. I want to thank Simon Muzio and Scott Guthrie, who encouraged me to finish the book.

I also want to thank Charlie Poole, who is one of the primary developers behind NUnit, for doing a technical review of the chapters concerning test-driven development.

I also want to thank Neil Rowe, who demonstrated incredible patience over the lifetime of this book. Yikes, this book took a long time to write.

Finally, I owe a huge debt of gratitude to my wife—Ruth.
