Book Description:This book gets you started with LINQ and shows how it will make your programming life easier by making use of new features from the .NET Framework 3.0. This book is split into seven chapters, each of which is dedicated to presenting a feature of LINQ and its usage in real-life scenarios.
Language Integrated Query (LINQ) is a new feature in Visual Studio 2008 that extends its query capabilities, using C# and Visual Basic. Visual Studio 2008 comes with LINQ provider assemblies that enable the use of LINQ with data sources such as in-memory collections, SQL relational databases, ADO.NET Datasets, XML documents, etc.
In Visual Studio 2008, Visual C# and Visual Basic are the languages that implement the LINQ language extensions. LINQ language extensions use the new standard query operators API, which is the query language for any collection that implements IEnumerable.
What you will learn from this book:
- Overview of new features for LINQ in .NET 3.0—partial methods,
expressions, anonymous types, initializers, and implicitly typed local
variables Accessing in-memory data structures using LINQ—lists, arrays, and dictionaries
- Directly querying the collections and filtering the required values
without using powerful filtering, ordering, and grouping capabilities
- Creating and manipulating XML data through .NET using XElement and XAttribute
- Creating and navigating XML trees using Functional Construction
- Importing and exporting data from dictionaries, databases, objects, and CSV files
- Creating and manipulating the database objects using the DataContext object
- Working with stored procedures, user-defined functions, handling
concurrency conflicts, and transactions during database updates
- Working with .NET framework data providers and DataSets
- Using DataSet for easier and faster querying of cached data
- Working with typed and un-typed XML trees using XSD
- Examining standard query operators provided by LINQ and using them to query data sources
- Implementing your own standard query operators
- Building an ASP.NET web application
Chapter 1 looks at the overall features of LINQ, and gives an
overview of different operators provided by LINQ to operate on objects,
XML, relational databases, etc.
Chapter 2 examines LINQ to Objects, which means that you can use
LINQ to query objects in a collection. Using this feature, you can
access in-memory data structures using LINQ. You can directly query
collections, and filter out required values without using powerful
filtering, ordering, and grouping capabilities.
Chapter 3 looks at LINQ to XML. It is a new in-memory XML
programming API to work against XML data. There are different ways of
creating XML trees in .NET. LINQ to XML is the new method of creating
and manipulating XML data through .NET. The properties and methods of
LINQ help in navigating and manipulating XML elements and attributes.
Chapter 4, which covers LINQ to SQL, takes care of translating
LINQ expressions into equivalent T-SQL, passing it on to the database
for execution, and then returning the results back to the calling
application. It reduces programming time a lot, and comes with two
different design-time tools, which are used for converting the
relational database objects into object definitions. It also has the
ability to create databases, and database objects.
Chapter 5 examines LINQ to DataSets. An ADO.NET DataSet provides
a disconnected data source environment for applications. It can be used
with multiple data sources. The DataSet has the flexibility of handling
data locally in cache memory where the application resides. The
application can continue working with a DataSet when it is disconnected
from the source and is not dependent on the availability of the data
source. The DataSet maintains information about the changes made to
data so that updates can be tracked and sent back to the database as
soon as the data source is available or reconnected.
Chapter 6 covers LINQ to XSD. It enhances XML programming by
adding the feature of typed views on un-typed XML trees. LINQ to XSD
gives a better programming environment by providing the object models
generated from XML schemas. This is called typed XML programming.
Chapter 7 looks at standard query operators provided by LINQ, and how you can use some of them against different data sources.

Pro LINQ Language Integrated Query in C Sharp 2008
Paperback: 600 pages

Book Description: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. LINQ will premier in Visual Studio 2008, and will become the next must–have skill for .NET developers.
Pro LINQ: Language Integrated Query in C# 2008 is all about code.
Literally, this book starts with code and ends with code. In most
books, the author shows the simplest example demonstrating how to use a method, 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 and
protoypes, it is a veritable treasury of LINQ examples.
Rather than obscure the relevant LINQ principles in code examples by focusing on a demonstration application you have no interest in
writing, Pro LINQ: Language Integrated Query in C# 2008 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 C# 2008 returns your investment is in the hours, and sometimes days, spent by the author determining why something may not work as expected.
Sometimes this results in an innocent looking 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, Pro LINQ:
Language Integrated Query in C# 2008 will attempt to entertain you on your journey through the wonderland of LINQ and C# 2008.
What you’ll learn:
- How to leverage all the new LINQ relevant C# 2008 language features including extension methods, lambda expressions, anonymous data types, and partial methods.
- How to use LINQ to Objects to query in–memory 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 co–exist 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.
