Description

Microsoft's Windows Workflow Foundation (WF) provides a framework for creating scalableapplications consisting of independent program units called activities. This course coversWF 4.5 and uses Visual Studio 2015, which provides a visual designer for creatingworkflows. The course begins with an overview of the concepts of workflow and theprogramming model provided by WF. The essentials of WF programming are then coveredfollowed by a systematic treatment of the major features of WF, including the Built-InActivity Library. Primitive and control flow activities are discussed, and the alternatives tohosting workflows are covered. Collection and parallel activities are covered. The creationof custom activities, both using the designer and code, is explained. Flowchart and statemachine activities are covered. Persistence and bookmarks are discussed. WorkflowServices, using Windows Communication Foundation (WCF) is covered. The courseconcludes with coverage of debugging, error handling, transactions and compensation.Comprehensive hands on exercises are integrated throughout to reinforce learning anddevelop real competency.

Prerequisites

C# programming experience.
