PROS: I liked the book, and learned a lot from it. It is both a very broad and deep view of C# and .NET, covering more than most other books. It has good explanations of things like delegates, properties, indexers, and differences between C# and java, C++ and other languages. The section on ADO (SQL Database classes) is especially good, tho it goes pretty fast. This is a professional book, not for beginning programmers, but especially good if you know java or C++ already (I know both, so it helped even more).
Between this book and the Microsoft web site, I now have a firm understanding of the basics of C#, and a start in learning a good chunk of .NET. Much more to do on learning .NET, of course.
CONS: The problem with the book was a lack of quality control -- many more errors in the code snippets and some detailed explanations than there should have been -- all someone has to do is copy them into a program and try compiling them, and verify it at least compiles! Some were corrected in the downloadable code, but still a lot that weren't (I got tired of submitting errata reports). There were even some simple speling errors (sic) that a simple spell checker could have caught! Jeez guys, come on!
I was forced to go to the Microsoft web site and get accurate data on many occasions. Lost confidence in Wrox.
I got the impression that much of the data had started in one of the other C# books, got edited, and now there are holes, references to code and items that don't exist, etc. More a fault of the editors than the original authors.
Wrox -- put some pressure on your quality control people! These aren't romance novels, people like us actually read these things and USE THEM!!!
