4253. Windows
Communication Foundation (WCF) Using Visual Basic (VS2008 and higher)
Rev. 2.0
Windows Communication Foundation (WCF) is Microsoft’s 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.
LEARNING OBJECTIVES
·
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
Prerequisite:
Students should have a good working knowledge of building .NET applications with
Visual Basic. Knowledge of building distributed systems and Web services will
also be an advantage.
