Workflow Activity Model

Windows Workflow Foundation (WF) in .NET Framework version 4 changes several development paradigms from previous versions; Workflows are now easier to create, execute, and maintain, and implement a host of new functionality.

The activity is now the base unit of creating a workflow, rather than using the SequentialWorkflowActivity or StatemachineWorkflowActivity classes.

The Go With The Flow blog has a posted a great 2-part story focused around working with the Workflow Foundation 4.0 Activity Model:
