Introduction to Workflow Services using .NET Framework 4
This hands-on lab is intended to introduce developers to writing workflow services using .NET Framework 4. You will examine the different messaging activities of Windows Workflow, and learn how to configure them to create a distributed application. This lab is built around a specific HR business scenario where candidates submit their applications and are hired or rejected based on an evaluation process.
What's New in WCF 4?
Windows Communication Foundation 4 includes a new feature that enables service discovery. Service discovery allows you to locate services on the same subnet using ad hoc discovery, or using a proxy to establish connections with servers regardless of where they are. In this lab you will create a simple chat application that will use both methods to learn about available services.
