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.

Hosting the WCF service in IIS


The WCF service is now hosted within WCF Service Host. You may still remember in the last chapter we had to start the WCF Service Host before we ran our test client. Not only do you have to start the WCF Service Host, you also have to start the WCF Test client and leave it open. This is not that nice. In addition, we will add another service later in this chapter to test distributed transaction support with two databases and it is not that easy to host two services with one WCF Service Host. So, in this section, we will first decouple our WCF service from Visual Studio to host it in IIS.

As we did in the previous chapter, you can follow these steps to host this WCF service in IIS:

  1. In Windows Explorer, go to the directory C:\SOAWithWCFandLINQ\Projects\DistNorthwind\DistNorthwindService.

  2. Within this folder create a new text file, ProductService.svc, to contain the following one line of code:

    <%@ServiceHost Service="MyWCFServices.DistNorthwindService.ProductService...
