Now that the .NET Framework 2.0, Visual Studio.NET 2005, SQL Server 2005 and all the associated free Express products are out in general use, it's a good time to look over the book marketplace and see what's out there. As one would expect, there has been a lot of "doctoring up" of previous titles targeted at the 1.1 platform with authors attempting to "get something out" with as little extra effort as possible (especially since sales, after a year or so, pretty much go down the drain along with royalty checks). However, there have been several titles previously targeted at the 1.1 platform that have been completely reworked, and this is one of them.

"Cookbook" is probably a bit of a misnomer here, in my opinion. What authors Michael Kittel and Geoffrey LeBlond have really done is to carefully examine all the major areas where an ASP.NET developer would need to have skills and have crafted quality solutions in each area - 125 solutions in all, and then categorized them all into 21 different categories for easy reference. So, it is not a book containing a bunch of cool "tips and tricks", but a foundation skills book. With this book at hand, the ASP.NET developer can quickly get up to speed on Master Pages, handling the display of tabular data, validation, user and custom controls, State, Security, configuration, caching, performance, and much more.

These are all "real world" examples and solutions, which makes them even more useful. We aren't creating funky "car" classes and fitting them with "AboutToBlow" events, we are writing real apps that do real things.

Here is a list of the major categories that this book covers:

As can be seen from the above Table of Contents listing, this is a book that covers a lot of material. I myself started with ASP.NET in 2000 with the very first BETA of Visual Studio, and at this late stage of the game, I'd consider myself pretty far up on the experience ladder. However with ASP.NET 2.0, there is a lot of new material to learn. Having a book like ASP.NET 2.0 Cookbook at one's side makes this process go a lot faster and cuts way down on the "developer frustration level".



For those who are "C# - Challenged", fear not. Every single example, even the "one line" examples, are presented in both VB.NET and C#. Of course, this makes the book bigger - nearly 1000 pages including the excellent index - but that's fine with me. Some of the more advanced features in .NET 2.0 such as Generics are also covered quite well. In particular, I found the sections on caching and WebParts most useful.

Here at eggheadcafe.com we have a credo - we don't write reviews on books that we don't think "make the grade", because we believe that doesn't provide a real service to our members and visitors. ASP.NET 2.0 Cookbook is clearly written, well-organized, and shows a remarkable degree of maturity from the two authors. I would highly recommend this book to any developer, whether beginner, intermediate or advanced, who feels they can use a comprehensive text that presents most of the major areas of ASP.NET for production quality applications in a single place. The sticker price on this book is US $54.95, and of course, one can find it at various online booksellers at reduced prices.
