.NET Training Overview
Windows Workflow Foundation (WF) is an API introduced with .NET 3.0 which allows you to execute and monitor business processes workflows directly in managed code. In this course, attendees will gain a clear understanding of the use of workflows, activities, and the visual tools which allow you to design them. We will also examine how to interact with the WF runtime engine, create custom activities and survey the integrated feature WF set.
.NET Training Audience:
Experienced .NET 2.0 software developers interested in learning about WF.
.NET Training Prerequisites
Understanding of Object Oriented Programming Using C# or VB.NET 2.0 development experience is required. No prior knowledge of WF is assumed.
