edition of this book was released shortly after the 2001 Tech·Ed conference in Atlanta, Georgia The latest edition of this text is a massive upgrade from the book’s prior editions that accounts for all of the new features found within NET 3.0 and NET 3.5 As you may know, NET 3.0 did not change the syntax of VB, but was simply an “augmentative release,” essentially providing three new APIs: Windows Presentation Foundation (WPF), Windows Communication Foundation (WCF), and Windows Workflow Foundation (WF) As you would expect, coverage of the “W’s” is included in the book you hold in your hands Unlike NET 3.0, NET 3.5 provides dozens of new VB language features and new NET APIs This edition of the book will walk you through all of this new material using the same readable approach (at least that is what I have been told!) as found in the prior editions Rest assured, you’ll find detailed coverage of Language Integrated Query (LINQ), the VB 2008 language changes (object initialization syntax, extension methods, anonymous types, etc.), and the numerous bells and whistles of Visual Studio 2008 The mission of this text is to provide you with a rock-solid foundation of the VB 2008 language and object-oriented programming techniques, as well as the core aspects of the NET platform Once you digest the information presented in these 35 chapters, you’ll be in a perfect position to apply this knowledge to your specific programming assignments, and you’ll be well equipped to explore the NET universe on your own terms ISBN-13: 978-1-59059-822-1 ISBN-10: 1-59059-822-9
