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.

About the Author
About the Reviewers


In this chapter, we have implemented a basic WCF service, hosted it within ASP.NET Development Server, and created a command line program to reference and consume this basic WCF service. At this point, you should have a thorough understanding as to what a WCF is under the hood. You will benefit from this when you develop WCF services using Visual Studio WCF templates or automation guidance packages. The key points covered in this chapter are:

  • A WCF service is a class library, which defines one or more WCF service interface contracts

  • The System.ServiceModel assembly is referenced by all of the WCF service projects

  • The implementations of a WCF service are just regular C# classes

  • A WCF service must be hosted in a hosting application

  • Visual Studio 2010 has a built-in hosting application for WCF services, which is called ASP.NET Development Server

  • A client application uses a proxy to communicate with WCF services

  • A configuration file can be used to specify settings for WCF services
