The document discusses Windows Workflow Foundation (WF), a framework that enables users to create system or human workflows in applications. WF allows for workflows within line-of-business apps, user interface page flows, document workflows, and more. A WF project can be created to define workflows as classes using C# or XML. The document provides a link to an MSDN tutorial about a simple expense report workflow that routes approvals based on amount and uses controls like If, Assign, and Sequence.
