Indicates that a rule is updating a variable, in order to cause reevaluation of affected rules.
Assembly: System.Workflow.Activities (in System.Workflow.Activities.dll)
This class is used to indicate to the rules engine that execution of this rule's set of actions causes a change to the field or property that is specified (or all fields and properties on an object), so that any rules that are dependent on this field or property can be reevaluated.
An Update call does not prevent other actions in the action block from executing. The set of fields/properties that are modified (specified through Update or by using RuleWriteAttributes on methods invoked) is used to determine chaining when the set of actions for this particular rule finishes executing.
