About the Authors
Cristian Darie is a software engineer with experience in a wide range of modern technologies, and the author of numerous technical books, including the popular
Beginning E-Commerce
series. Having worked with computers since he was old enough to use a keyboard, he initially
tasted programming success with a prize in his first programming contest at the age of 12.
From there, Cristian moved on to many other similar achievements, and is now studying
distributed application architectures for his PhD.
He always loves hearing feedback about his books, so don't hesitate to drop him a “hello”
message when you have a spare moment. Cristian can be contacted through his personal web
site at http://www.cristiandarie.ro.
Wyatt Barnett leads the in-house development team for a major industry trade association
in Washington DC. When not slinging obscene amounts of C# and SQL at a few exceedingly
large monitors, he is most often spotted staring at HDTV and other forms of entertainment
in local watering holes. He also writes for SitePoint's .NET blog,
The Daily Catch
