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.

In this chapter, we have learned and clarified many concepts related to SOA, web services, and WCF. The key points in this chapter are:

  • SOA is an architectural design pattern

  • Web services are the most popular and practical way of realizing SOA today

  • There are many standards and specifications for web services, including (but not limited to) WSDL, SOAP, WS-I Profiles, and various WS-* standards

  • WCF is a better technology for developing SOA services

  • A WCF service has at least one service endpoint

  • A WCF service endpoint has an address, a binding, and a service contract

  • A WCF service can be self-hosted or can be hosted in a managed or an unmanaged application

  • A WCF service can publish metadata and communicates with client applications through channels

  • .NET Framework 3.0 or above is required to develop and run WCF service applications

  • Visual Studio 2008 and 2010 are the preferred IDEs for WCF service application development
