Lately, I’ve been spending my evenings with Windows Workflow. Hello, Workflow is a new, feature length introduction to WinWF.
The primary building block in Windows Workflow is the activity. All activities in WinWF derive from an Activity base class. Activities compose the steps, or tasks in a workflow. We can arrange activities into a hierarchy and feed the activities to the workflow engine as instructions to execute. The activities can direct workflows involving both software and humans.
