This means that he spends most of his time traveling around the country helping clients utilize Microsoft developer technologies effectively. Jonathan has been programming for more than 13 years and has worked with numerous technologies, including but not limited to C, C++, Visual Basic, COM, COM+, SQL, ASP, and, of course, all aspects of .NET. As well as programming, Jonathan also spent part of his career working as a Microsoft Trainer, delivering the full suite of Microsoft Official Curriculum courses and specially-designed courses also. Jonathan tries to keep his blog ( http://blogs.msdn.com/jonathanswift) up to date, but feels that writing a book is a very good excuse for not doing so. (Other popular excuses including playing the XBox and washing his hair.) When he’s not working, Jonathan spends all of his time with his wife and kids, and occasionally gets to exercise his pilot’s license at the flying club. Chris Barker works as an Application Development Consultant for Microsoft in the United Kingdom ( www.microsoft.com/uk/adc). He spends his days traveling around the country visiting customers and consulting on development practices on the Microsoft platform. More recently, his interest has been captured by RIA development, and as a result, he has delivered several customer workshops on Silverlight. Away from the office, Chris likes to get out and about in his home county of Derbyshire, riding a bike, kicking a football, and sinking a few pints of real ale. Dan Wahlin (Microsoft Most Valuable Professional for Connected Systems) is a .NET development instructor and architecture consultant at Interface Technical Training ( www.interfacett.com). Dan founded the XML for ASP.NET Developers web site ( www.xmlforasp.net), which focuses on using ASP.NET, Silverlight, AJAX, and XML Web Services in Microsoft’s .NET platform. He’s also on the INETA Speaker’s Bureau and speaks at several conferences. Dan has authored/co-authored numerous books over the years on .NET technologies with his latest being Professional ASP.NET 3.5 AJAX and Professional Silverlight 2 for ASP.NET Developers. Dan also writes for several online technical newslet- ters, blogs at http://weblogs.asp.net/dwahlin, and updates what he’s up to from time to time at www.twitter.com/danwahlin. When he’s not working with technology, he enjoys sports and writ- ing and recording music to relax a little — http://weblogs.asp.net/dwahlin/archive/tags/ Music/default.aspx . Salvador Alvarez Patuel has been in the industry for more than 13 years. Currently a senior application development consultant (ADC) at Microsoft, helping customers to architect and build complex solutions using Microsoft technologies in the United Kingdom. Salvador has also been delivering multiple tech- nical sessions around EMEA on Windows Mobile development and has been answering questions on many ask-the-experts events. Before joining Microsoft, he was the main technical architect for real-time engines on popular auctions, TV channels, and the gaming industry. He holds a software engineering degree from his native Argentina and a specialization in artificial intelligence. When Salva is not think- ing about ones and zeroes, he enjoys climbing, windsurfing, and recently trying to learn how to play golf. 77751ffirs.indd 8 12/19/08 8:35:59 AM www.it-ebooks.info Credits Executive Editor Robert Elliott Development Editor Kelly Talbot Technical Editor Dave Friedel Senior Production Editor Debra Banninger Copy Editor Cate Caffrey Editorial Manager Mary Beth Wakefield Production Manager Tim Tate Vice President and Executive Group Publisher Richard Swadley Vice President and Executive Publisher Joseph B.
