For years, I have been on the other side as the reader of hundreds of books on topics ranging from video game programming to the latest version of ASP.NET. I’ve never given much thought about how much work actually goes into the writing and producing one of those aforementioned books. Now, as a first-time writer who has completed his first book, I can safely say I’ll never take the hard work that authors and publishers perform for granted again. With that said, I want to take the time to thank everyone who helped to make this book possible. First, I want to thank my wife, who despite being pregnant with a due date scheduled right smack in the middle of writing this book, continued to encourage the work that I was doing and put up with many weekends of marathon writing sessions. Needless to say, my chore list has grown since the book started. Next, I want to thank my daughter Tabetha, who I could only take to one Mets game this year because of my busy schedule. Luckily, the team was terrible so it wasn’t much of a sacrifice. Completing a book like this one involves months of hard work from not just me but also the hard- working team at Wrox Press. I can’t even begin to convey just how dedicated and professional the Wrox Press team is when it comes to publishing new books but I will make an attempt by thanking those who were directly involved in the completion and success of Silverlight 4 Problem-Design- Solution. For starters, I want to thank Maureen Spears who was the Project Editor for this book. As a first time writer, it is imperative to be paired with an editor who has a lot of patience. Luckily, I had Maureen on my side throughout the process. Whether it was a breaking change in a beta release or some other crazy issue threatening to sabotage me from hitting a deadline, Maureen was always the calm voice of reason that would assure me that there was nothing to worry about and these things happen all the time. More often than not, just knowing that I wasn’t the only writer to hit these roadblocks was usually enough to get me to the next milestone. In addition to Maureen, I also had a wonderful Copy Editor in Nancy Rappaport, who no doubt had her hands full with this project. Thanks to her diligent work, the chapters make logical sense and are grammatically correct. As a full-time software developer, grammar isn’t always the first thing on my mind when I write. Of course, although my full-time focus is on programming, when you write a technical book it is vital to have the content reviewed by another professional software developer to ensure that the author doesn’t lose the audience along the way. My Technical Editor, Jonathan Marbutt, was an invaluable resource, ensuring that the chapter code not only compiled but also by reviewing the topics discussed in the accompanying chapter. Finally, I want to thank the two people from Wrox who made this book possible in the first place. Thanks to Paul Reese, the Acquisitions Editor, who from the very beginning was there to help me convert my idea for a book into a real proposal that would eventually kick off the project. Lastly, I’d like to thank Jim Minatel, the Associate Publisher, who I first contacted with the idea. Thanks again, Paul and Jim, for taking the time to listen to my original idea, for providing me with this great opportunity, and for taking a chance on this first-time writer. 534045ffirs.indd 8 3/16/10 9:35:31 AM www.it-ebooks.info [...]...
