Represents a task to be completed when a transition is executed. An action is associated with a transition through the AddAction(EnumActionType, String) method.

There are actions for common operations in the content tree, such as checking in a page and marking a page for publish. If the built-in actions are not adequate, developers can create custom workflow actions. Custom workflow actions assemblies must be put in App_Data/xml/custom/plugins/CustomWorkflowActions directory. The actual Action class must implement the ICustomWorkflowAction interface. The custom action uses its full class name as the value of the ProgID attribute and calls the Execute method to perform the action.

The actions associated with a transition are executed in the order in which they are added to the transition. If an action fails to execute, the transition will not complete. The workflow remains in the WorkState it was in before the transition executed.
