NoteNote

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

The SequentialWorkflowActivity is a SequenceActivity with Initialized and Completed events for optional processing of parameters. This makes it particularly useful as a top-level activity when you design sequential-style workflows.

The SequentialWorkflowActivity is a CompositeActivity, which means the SequentialWorkflowActivity can contain other activities.
