Legacy Workflow Activities
[This is prerelease documentation and is subject to change in future releases. Blank topics are included as placeholders.]
Windows Workflow Foundation (WF) includes a default set of activities that provide functionality for control flow, conditions, event handling, state management, and communicating with applications and services. When designing workflows, you can use the system-provided activities that are provided by the Windows Workflow Designer, or you can create your own custom activities.
The following table lists the Windows Workflow Foundation framework out-of-box activity set. Many, but not all, of these activities are represented by activity designers that can be accessed from the Toolbox of the Workflow Designer. To create an activity, drag its designer from the Toolbox and drop it on the design surface.
| Activity | Description |
|---|---|
Used with the HandleExternalEventActivity activity for input and output communications with a local service. For more information, see Using the CallExternalMethodActivity Activity. |
|
Used to contain cleanup logic for a composite activity canceled before all the composite activity's children are finished executing. For more information, see Using the CancellationHandlerActivity Activity. |
|
Enables you to add Visual Basic or C# code to your workflow. For more information, see Using the CodeActivity Activity. |
|
A compensatable version of SequenceActivity. For more information, see Using the CompensatableSequenceActivity Activity. |
|
A compensatable version of TransactionScopeActivity. For more information, see Using the CompensatableTransactionScopeActivity Activity. |
|
Enables you to call code to undo or to compensate for operations already performed by the workflow when an error occurs. For more information, see Using the CompensateActivity Activity. |
|
A wrapper for one or more activities that perform compensation for a completed TransactionScopeActivity activity For more information, see Using the CompensationHandlerActivity Activity. |
|
Executes child activities based on a condition that applies to the ConditionedActivityGroup activity itself and based on conditions that apply separately to each child. For more information, see Using the ConditionedActivityGroup Activity. |
|
Enables you to build delays in your workflow that are based on a time-out interval. For more information, see Using the DelayActivity Activity. |
|
Wraps one or more activities that are executed when a specified event occurs. For more information, see Using the EventDrivenActivity Activity. |
|
Provides a framework for associating events with an activity. For more information, see Using the EventHandlersActivity Activity. |
|
Executes its main child activity concurrently with an EventHandlersActivity. For more information, see Using the EventHandlingScopeActivity Activity. |
|
Used to handle an exception of a type that you specify. For more information, see Using the FaultHandlerActivity Activity. |
|
Represents a composite activity that has an ordered list of child activities of type FaultHandlerActivity. For more information, see Using the FaultHandlersActivity Activity. |
|
Used in conjunction with the CallExternalMethodActivity activity for input and output communications with a local service. For more information, see Using the HandleExternalEventActivity Activity. |
|
Tests a condition on each branch and performs activities on the first branch for which the condition equals true. For more information, see Using the IfElseActivity Activity. |
|
Represents a branch of an IfElseActivity. For more information, see Using the IfElseBranchActivity Activity. |
|
Enables your workflow to invoke a Web service. For more information, see Using the InvokeWebServiceActivity Activity. |
|
Enables your workflow to invoke another workflow. For more information, see Using the InvokeWorkflowActivity Activity. |
|
A composite activity that contains only EventDrivenActivity child activities. For more information, see Using the ListenActivity Activity. |
|
Provides a way to schedule two or more child SequenceActivity activity branches for processing at the same time. For more information, see Using the ParallelActivity Activity. |
|
Use to represent a collection of rules. A rule consists of conditions and resulting actions. For more information, see Using the PolicyActivity Activity. |
|
Creates multiple instances of a single child activity. For more information, see Using the ReplicatorActivity Activity. |
|
Provides a simple way to link multiple activities together for sequential execution. For more information, see Using the SequenceActivity Activity. |
|
Specifies a transition to a new state. For more information, see Using the SetStateActivity Activity. |
|
Represents a state in a state machine workflow. For more information, see Using the StateActivity Activity. |
|
Used in a StateActivity activity as a container for child activities that are executed when leaving the StateActivity activity. For more information, see Using the StateFinalizationActivity Activity. |
|
Used in a StateActivity activity as a container for child activities that are executed when entering the StateActivity activity. For more information, see Using the StateInitializationActivity Activity. |
|
Suspends the operation of your workflow to enable intervention in the event of some error condition that requires special attention. For more information, see Using the SuspendActivity Activity. |
|
Executes contained activities sequentially in a synchronized domain. For more information, see Using the SynchronizationScopeActivity Activity. |
|
Enables you to immediately end the operation of your workflow in the event of an error condition. For more information, see Using the TerminateActivity Activity. |
|
Enables you to capture business exceptions thrown as part of the process metadata for a workflow. For more information, see Using the ThrowActivity Activity. |
|
Provides a framework for transactions and exception handling. For more information, see Using the TransactionScopeActivity Activity. |
|
Enables you to model the occurrence of a Web service fault. For more information, see Using the WebServiceFaultActivity Activity. |
|
Receives data from a Web service. For more information, see Using the WebServiceInputActivity Activity. |
|
Responds to a Web service request made to a workflow. For more information, see Using the WebServiceOutputActivity Activity. |
|
Enables your workflow to loop until a condition is met. For more information, see Using the WhileActivity Activity. |
