Course Description
Microsoft's
Windows Workflow Foundation (WF) provides a framework for
creating scalable applications consisting of independent program
units called activities. This course covers WF 4.5 and uses
Visual Studio 2015, which provides a visual designer for
creating workflows. The course 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. Primitive and control flow activities
are discussed, and the alternatives to hosting workflows are
covered. Collection and parallel activities are covered. The
creation of custom activities, both using the designer and code,
is explained. Flowchart and state machine activities are
covered. Persistence and bookmarks are discussed. Workflow
Services, using Windows Communication Foundation (WCF) is
covered. The course concludes with coverage of debugging, error
handling, transactions and compensation. Comprehensive hands on
exercises are integrated throughout to reinforce learning and
develop real competency.
Course Prerequisites
C# programming experience.
