摘要:
Providing data bound workflow activities to model messaging between a workflow instance and a workflow host. The workflow author associates a data source with each data bound activity in a workflow without specifying details of the underlying messaging technology. The data bound activity in the workflow instance communicates with a data source service in the workflow host to exchange data.
摘要:
Building a componentized workflow model via an application programming interface. Each step of the workflow is modeled as an activity that has metadata to describe design time aspects, compile time aspects, and runtime aspects of the workflow step. A user selects and arranges the activities to create the workflow via the application programming interfaces. The metadata associated with each of the activities in the workflow is collected to create a persistent representation of the workflow. Users extend the workflow model by authoring custom activities. Users also compile the workflow via the application programming interface.

Representing a componentized workflow model via a declarative markup language. Each step of the workflow is modeled as an activity that has metadata to describe design time aspects, compile time aspects, and runtime aspects of the workflow step. A user selects and arranges the activities to create the workflow via user interfaces or application programming interfaces. The metadata associated with each of the activities in the workflow is collected to create a persistent representation of the workflow. Users extend the workflow model by authoring custom activities.
摘要:
Modifying a componentized workflow model during execution of the workflow. Each step of the workflow is modeled as an activity that has metadata to describe design time aspects, compile time aspects, and runtime aspects of the workflow step. A user selects and arranges the activities to create the workflow via user interfaces or application programming interfaces. Metadata is associated with each of the activities in the workflow. During execution of the workflow, the user modifies the metadata to affect execution of the workflow without recompiling the workflow.
摘要:
Enabling creation of control flow patterns in a workflow via continuations. Each continuation represents an activity execution context for an activity executing in the workflow by a workflow engine virtualizing a managed execution environment. Responsive to a request, the activity execution context is recreated via the continuation and the activity is executed within the recreated context.

摘要:
Asynchronous fault handling for a workflow. A state automaton for an activity in the workflow is defined. The state automaton includes at least an executing state, a faulting state, and a closed state and classifies an execution lifetime of the activity. The activity is defined to include work items and includes an execution hierarchy for the work items. Each work item includes an operation for executing a portion of the activity. Each work item is transitioned to the executing state. The included operation of transitioned work items is executed in the executing state. One or more of the transitioned work items are identified in response to the faulting event as a function of the execution hierarchy and the included operation. The faulting event is asynchronously handled by transitioning the one or more identified work items to the faulting state while executing the included operation of the remaining transitioned work items.
