System_CAPS_noteNote

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

The following string is added to the event log when this exception is thrown: Event "{1}" on interface type "{0}" for instance id "{2}" cannot be delivered.

When using a state machine workflow, you might get an exception with the message "Queue '{0}' is not enabled." This happens when the current state of the state machine does not know how to handle a specific event. For example, when some state other than the current state contains the EventDrivenActivity that contains the HandleExternalEventActivity that is represented by the queue '{0}'.
