Introduction to WCF Using C#

Windows Communication Foundation (WCF) is Microsofts new framework for building distributed systems. It unifies and builds on the diverse set of existing distribution mechanisms, which include ASP.NET Web services and .NET Remoting. WCF enables developers to produce highly configurable, secure, reliable and transactional services using a single simplified programming model. And since WCF supports the WS-* series of Web service standards, it enables simple interoperation with other platforms and technologies. This course covers the essentials of the technology and includes a large number of working examples and lab exercises.

The course uses .NET 3.5 and Visual Studio 2008. An earlier version of the course, Rev. 1.1, uses Visual Studio 2005 and is still available.

• Prerequisite: Students should have a good working knowledge of building .NET applications with C#. Knowledge of building distributed systems and Web services will also be an advantage.

• Learn what WCF is, and how it unites existing distribution mechanisms
• Gain an understanding of what ABC (Address, Binding, Contract) means for WCF services
• Learn how to implement WCF services and clients

Course exercises require Microsoft .NET 3.5 and Visual Studio 2008 Standard Edition or higher. The preferred operating system is Windows XP Professional with Internet Information Services. See the appropriate course Setup Guide for details.

A good minimal hardware profile for this course consists of a 2 GHz or better CPU, 512 MB of RAM, and at least 4 GB of free disk space for tools installation and courseware.
