Overview of this book

WCF is the Microsoft model for building services, whereas LINQ to Entities is the Microsoft ORM for accessing underlying data storage. Want to learn both? You would normally have to dig through huge reference tomes—so wouldn't you agree that a simple-to-follow practical tutorial on WCF and LINQ to Entities is the way to get ahead?This book is the quickest and easiest way to learn WCF and LINQ to Entities in Visual Studio 2010. WCF and LINQ to Entities are both powerful yet complex technologies from Microsoft—but you will be surprised at how easily this book will get you get up and running with them.Mastery of these two topics will quickly enable you to create Service-Oriented applications, and allow you to take your first steps into the world of Service Oriented Architecture without becoming overwhelmed.Through this book, you will learn what's going on behind the scenes with WCF, and dive into the basic yet most useful techniques for LINQ to Entities. You will develop three real-world multi-tiered WCF services from beginning to end, with LINQ to Entities being used in the data access layer of the services. Various clients including windows console applications, the WCF Test Client, Windows Form applications and WPF applications will be created to test these WCF services.

Creating the HelloWorld solution and project

Before we can build the WCF service, we need to create a solution for our service project. We also need a directory in which we will save all the files. Throughout this book, we will save our project source codes in the C:\SOAWithWCFandLINQ\Projects directory. We will have a subfolder for each solution we create, and under this solution folder, we will have one subfolder for each project.

For this HelloWorld solution, the final directory structure is shown in the following image:


You don't need to manually create these directories with Windows Explorer; Visual Studio will create them automatically when you create the solutions and projects.

Now follow these steps to create our first solution and the HelloWorld project:

  1. Start Visual Studio 2010. If the Open Project dialog box pops up, click on Cancel to close it.

  2. Go to menu File | New | Project. The New Project dialog window will appear.

  3. From the left-hand side of the window (Installed Templates...
