ASP.NET 3.5 is Microsoft s next generation web-development technology building upon the successful ASP.NET 2.0 platform and augmenting it with a number of key new features. The most prominent of these are ASP.NET AJAX (formerly code-named Atlas) for improving user-interface design and Language Integrated Query (LINQ) for revolutionizing the way .NET code interacts with database information. This book is the second edition of Matthew MacDonald and Mario Szpuszta s well-regarded title. It has been comprehensively updated to provide detailed coverage of all.NET 3.5 s new features within the same framework and writing style that made the previous editions so successful.
