Also, special thanks to Adnan Masood, Zubair Ahmed, and Alvin Lau for technically reviewing the book, providing feedback, and correcting numerous mistakes.

Last but not the least, thanks to the editorial and project team at Packt Publishing for giving me the opportunity to write this book, and also being patient and understanding through the process of writes, re-writes, technical edits, as well as cases of missed deadlines.

I would like to thank my loving, patient, and amazing wife Christie for being my rock and providing a foundation which has allowed us to grow a beautiful family while enduring the sometimes overbearing demands of my career. I'm also grateful to my wonderful children, Sarah and Ricky for tolerating the many lost nights and weekends holed up in my home office working on this book.

I would also like to thank Mickey Williams, VP Technology Platform Group at Neudesic for his support in taking on this project along with his words of encouragement and (always timely) sense of humor along the way.

Last but not least, I would like to thank my friend and co-author, Hammad Rajjoub for inviting me to participate in this project and trusting me to help carry out his vision for this book. Hammad and I both share a labor of love as it applies to the Microsoft distributed technology stack affectionately (and somewhat nostalgically) known as "Connected Systems" and this book is both a reflection and an acknowledgment of the tremendous work the WCF, WF, and Dublin teams have done in putting these tremendous capabilities within reach of developers tasked with solving tough distributed challenges today.
