About the Authors
Hi, my name is Bill Sempf, and I am a software architect. Although I used to
hate the term architect, it’s clearly the only thing out there that defines what
I do. My breadth of experience includes business and technical analysis,
software design, development, testing, server management and maintenance,
and security. In my 17 years of professional experience, I have participated
in the creation of well over 200 applications for large and small companies,
managed the software infrastructure of two Internet service providers,
coded complex software happily in every environment imaginable, and made
mainframes talk to cellphones. In short, I make the technology products that
people are using every day play nicely together.
I started playing with computers in 1979 and haven’t looked back since. In
1985, I was helping my father (also named Bill) manage Apple IIe systems at
the local library. Since then, I have built applications for the likes of Bank
One, Lucent Technologies, Nationwide Insurance, and Sears, Roebuck and
Co. I am the author of Windows 8 Programming with HTML5 For Dummies and
Visual Basic 2008 For Dummies; a coauthor of Effective Visual Studio.NET,
Professional ASP.NET Web Services, and Professional VB.NET; a frequent
contributor to MSDN, Builder.com, Hardcore Web Services, Cloud Computing
Journal, Inside Web Development Journal, and Intranet Journal; and have
recently been an invited speaker for the ACM and IEEE, DevEssentials, the
International XML Web Services Expo, and the Association of Information
Technology Professionals. I am a graduate of The Ohio State University with a
bachelor’s of science degree in business administration, a Microsoft Certified
Professional, a Certified Internet Business Strategist, and a Certified Internet
Webmaster. My company is Products Of Innovative New Technology (usually
called POINT), and you can reach me at [email protected].
Chuck Sphar escaped the Microsoft C++ documentation camps after six
years of hard labor as a senior technical writer. You can reach Chuck for
praise and minor nits at [email protected]. His C# material web
page (references throughout the book) is http:://csharp102.info.
Stephen R. Davis, who goes by the name Randy, lives with his wife and son
near Dallas, Texas.

Dedication
This edition is dedicated to the great folks at the For Dummies team at John
Wiley & Sons. They genuinely care about creating awesome books for the
developer community that are both technically sound and mildly humorous.
Can’t beat that combination.
Also, for Gabrielle, Adam, and Kaelan, who had to put up with another six
months of Daddy hiding in the basement.
Author’s Acknowledgments
A lot of people work to make a book of this size. Don’t think, just because the
authors are listed on the front page, that they conceived every idea in the
book. It takes a community.
First, thanks to Chuck Sphar and Randy Davis for the fantastic source
material that is the backbone of this book. I learned much just editing the
first two minibooks for use in this All-in-One. Also, thanks to Kelly Ewing and
Katie Feltman for their editorial expertise.
A number of community members had a huge part in the creation of this
book. Carey Payette and Phil Japikse built Book V (about WPF) basically
from the goodness of their hearts, and I couldn’t have completed it without
them — my WPF skills aren’t worth writing about. These two get the award
for Biggest Contribution, and I thank them both.
Chuck Sphar, aside from being one of the original authors of the book, also
tech edited this edition. He did a truly awesome job and discovered many
a hidden gotcha. Thanks to him for his effort. As always, thanks to my wife,
Gabrielle, for her support. Sometimes I just can’t believe how lucky I am.
