In this chapter we've explored some of the details of the
SequentialWorkflowActivity, including how to communicate and pass data between a sequential workflow and its host, and how to handle faults inside a sequence of activities.
Sequential workflows inherit most of their behavior from the
SequenceActivity class, which can appear in more than just a sequential workflow. As we will see later in the book, sequential activities are also important in the other primary type of workflow, the event-driven workflow.
