4253. Introduction to WCF
Using Visual Basic
Rev. 1.1
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.
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
Course Duration: 3 days
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.
