Product Description
LINQ is the project name for a set of extensions to the .NETFramework that provide a generic approach to querying data fromdifferent data sources. LINQ will premier in Visual Studio 2008, andwill become the next must–have skill for .NET developers. For moreinformation about LINQ, you can check out the author’s portal atwww.linqdev.com.
Pro LINQ: Language Integrated Query in C# 2008 is all about code.
Literally, this book starts with code and ends with code. In mostbooks, the author shows the simplest example demonstrating how to use amethod, but they so rarely show how to use the more complex prototypes.Pro LINQ: Language Integrated Query in C# 2008 is different.Demonstrating the overwhelming majority of LINQ operators andprotoypes, it is a veritable treasury of LINQ examples.
Rather than obscure the relevant LINQ principles in code examples byfocusing on a demonstration application you have no interest inwriting, Pro LINQ: Language Integrated Query in C# 2008 cutsright to the chase of each LINQ operator, method, or class. However,where complexity is necessary to truly demonstrate an issue, theexamples are right there in the thick of it. For example, code samplesdemonstrating how to handle concurrency conflicts actually createconcurrency conflicts so you can step through the code and see themunfold.
Most books tell you about the simple stuff, while few books warn you of the pitfalls. Where Pro LINQ: Language Integrated Query in C# 2008returns your investment is in the hours, and sometimes days, spent bythe author determining why something may not work as expected.Sometimes this results in an innocent looking paragraph that may takeyou a minute to read and understand, but took days to research andexplain.
Face it, most technical books while informative, are dull. LINQ need not be dull. Written with a sense of humor, Pro LINQ: Language Integrated Query in C# 2008 will attempt to entertain you on your journey through the wonderland of LINQ and C# 2008.
