.NET Training Overview
Windows Communication Foundation (WCF) is an API used to build distributed applications using .NET 3.0 (and higher). WCF was designed to expose the current multitude of Windows remoting APIs (web services, MSMQ, TCP, peer-to-peer, etc) from a single unified toolkit. In this course, attendees will examine the overall WCF programming model, binding choices, host options, security issues and the use of declarative markup to specify the underlying infrastructure.
.NET Training Audience:
Experienced .NET 2.0 software developers interested in learning about WCF.
.NET Training Prerequisites
Understanding of Object Oriented Programming Using C# or VB.NET 2.0 development experience is required. No prior knowledge of WCF is assumed.
