LINQ is the project name for a set of extensions to the .NET
Framework that provide a generic approach to querying data from
different data sources. LINQmade its debutin Visual Studio 2008,
andbecamea musthave skill for .NET developers. For more information
about LINQ, you can check out www.linqdev.com.
Starting with code and ending with code and tailored for the VB
language, Pro LINQ: Language Integrated Query in VB 2008 is a
veritable treasury of LINQ examples that will save you hours, even
days, of research time. Keeping you focused on the relevant LINQ
principles, expert author Joseph Rattz, Jr., and VB specialist
Dennis Hayes provide examples for complex models that you won't
find anywhere else.
In most books, you'll find plenty of simple examples to
demonstrate how to use a method, but authors rarely show how to use
the more complex prototypes. Pro LINQ: Language Integrated Query in
VB 2008 is different. Demonstrating the overwhelming majority of
LINQ operators and protoypes, Joseph Rattz, Jr., and Dennis Hayes
condense their extensive experience and expertise into a desk
companion that is essential for any serious .NET professional.
Rather than obscure the relevant LINQ principles in code
examples by focusing on a demonstration application you have no
interest in writing, this book cuts right to the chase of each LINQ
operator, method, or class. However, where complexity is necessary
to truly demonstrate an issue, the examples are right there in the
thick of it. For example, code samples demonstrating how to handle
concurrency conflicts actually create concurrency conflicts so you
can step through the code and see them unfold.
Most books tell you about the simple stuff, while few books warn
you of the pitfalls. Where Pro LINQ: Language Integrated Query in
VB 2008 returns your investment is in the hours, and sometimes
days, spent by the authors determining why something may not work
as expected. Sometimes this results in an innocentlooking paragraph
that may take you a minute to read and understand, but took days to
research and explain.
Face it, most technical books while informative, are dull. LINQ
need not be dull. Written with a sense of humor, this book will
attempt to entertain you on your journey through the wonderland of
LINQ and VB 2008. What you'll learn How to leverage all the
LINQrelevant VB 2008 language features, including extension
methods, lambda expressions, anonymous data types, and partial
methods How to use LINQ to Objects to query inmemory data
collections such as arrays, ArrayLists, and Lists to retrieve the
data you want Why some queries are deferred, how a deferred query
can bite you, and how you can make deferred queries work for you
How to use LINQ to XML to revolutionize your creation,
manipulation, and searching of XML data How to query DataSets with
LINQ to DataSet so you can coexist with legacy code and use LINQ to
query databases other than SQL Server How to query databases with
LINQ to SQL, write your own entity classes, and understand how to
handle concurrency conflicts Who this book is for

not need to be up on all the latest VB features to understand the
