WCF 4.0 Multi-tier Services Development with LINQ to Entities

By: Mike Liu

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. By the end of this book, you will be 100% confident that you know WCF and LINQ to Entities, not only in theory, but with sound real-world experience.

Creating the LINQNorthwind solution


The first thing we need to do is to create a test solution. In this chapter we will modify a copy of our last solution, RealNorthwind, to test LINQ to Entities in the data access layer.

Note that you can create the solution from scratch if you like or you can just copy and reuse the RealNorthwind solution without any modification. If you are going to reuse the RealNorthwind solution, wherever you see LINQNorthwind in this chapter, you can just replace it with RealNorthwind and continue.

Here we will make a copy first then rename and change all the words Real to LINQ so that we will have a dedicated solution to test LINQ to Entities.

Now follow these steps to create this solution:

  1. Open Windows Explorer and create a new folder, LINQNorthwind, under C:\SOAWithWCFandLINQ\Projects.

  2. Copy all files and folders from the RealNorthwind project folder C:\SOAWithWCFandLINQ\Projects\RealNorthwind to the new folder C:\SOAWithWCFandLINQ\Projects\LINQNorthwind.

  3. Under the...
