PDC 2008 Experience: Day 3: WCF 4

Challenges

• Work is increasingly distributed
• Coordination code created complexity
• Coordinating messages with application state
• Coordinating call to a database or another service
• Coordinating rain day scenarios
• Management and tracking of distributed work is difficult

What is WF (Dub F)?

• WF programs coordinate work with minimal ceremony
• Activities
• Activities are the primitive abstraction for behavior
• Activities define arguments to declare the type of data that can flow into or out of an activity
• Activities are composable with other activities
• Activities bind arguments to in-scope variable
• Runtime
• Tooling
