Raised whenever a change is made to the contents of this ICollection.
Assembly: System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)
In this context, adding or removing members raises the event. Modifying a member does not raise this event.
When you create an ActivityCollection delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.
- Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.
