AppFabric Workflow Management Service

The second AppFabric Windows service is the Workflow Management service, which the hosting services use to manage instances of workflows.  The Workflow Management service activates a workflow service instance in an instance store when the instance is eligible to be activated.  The Workflow Management service retrieves commands from a message queue that is written to by an instance control provider, executes the commands, and then deletes commands from the queue if the command execution is successful.
