Chapter 24: Programming with the LINQ APIs

Chapter 14 introduced you to the LINQ programming model, specifically LINQ to Objects. Here,

you will deepen your understanding of Language Integrated Query by examining how to apply

LINQ queries to relational databases, DataSet objects, and XML documents. Along the way, you will

learn the role of data context objects, the sqlmetal.exe utility, and various LINQ-specific aspects of

Visual Studio 2008.

Chapter 25: Introducing Windows Communication Foundation

.NET 3.0 introduced a brand-new API, WCF, that allows you to build distributed applications,

regardless of their underlying plumbing, in a symmetrical manner. This chapter will expose you to

the construction of WCF services, hosts, and clients. As you will see, WCF services are extremely

flexible, in that clients and hosts can leverage XML-based configuration files to declaratively specify

addresses, bindings, and contracts.

Chapter 26: Introducing Windows Workflow Foundation

In addition to WCF, .NET 3.0 also introduced an API, WF, that allows you to define, execute, and

monitor 

workflows to model complex business processes. Here, you will learn the overall purpose

of Windows Workflow Foundation, as well as the role of activities, workflow designers, the workflow

runtime engine, and the creation of workflow-enabled code libraries.
