Microsoft’s Windows Workflow Foundation (WF) provides a framework for creating scalable applications consisting of independent program units called activities. WF 4 was a major rewrite of this technology, offering significantly higher performance and making it easier to create and execute workflow applications. WF 4.5 contains new activities, designer capabilities, and a new workflow development model (state machines). It also supports the use of C# expressions in C# workflows. This four-day course covers WF 4.5 and uses Visual Studio 2013, which provides a visual designer for creating workflows.
This Windows Workflow Foundation Using C# training class begins with an overview of the concepts of workflow and the programming model provided by WF. The essentials of WF programming are then covered, followed by a systematic treatment of the major features of WF, including the Built-In Activity Library. Other topics covered in this course include primitive and control flow activities, the alternatives to hosting workflow, collection and parallel activities, the creation of custom activities, flowchart and state machine activities, persistence and bookmarks, Workflow Services and using Windows Communication Foundation (WCF). The course concludes with a discussion of debugging, error handling, transactions and compensation.
