Windows Workflow Foundation
Windows Workflow Foundation (WWF) is a .NET technology for defining, designing, hosting, and running processes as workflows. It allows modeling of both human and application workflows. WWF supports sequential, flowchart, and state machine based workflows. Workflows can be authored visually using the Visual Studio designer or declaratively using XAML. The WWF runtime handles workflow execution and provides features like persistence, hosting, and tracking. Workflows can be hosted in WorkflowServices or WorkflowManager and are suitable for long running business processes, integration, and automation scenarios.
