MsmqBindingElementBase::ExactlyOnce Property
Gets or sets a value that specifies whether messages sent with this binding have exactly once assurances.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Property Value
Type: System::Booleantrue if messages sent with this binding have exactly once assurances; otherwise, false.
ExactlyOnce, when set to true, indicates that Message Queuing (MSMQ) ensures that a sent message is delivered to the receiving message queue once and only once, and, if delivery fails, the message is sent to the dead-letter queue, depending on the DeadLetterQueue property setting. Setting ExactlyOnce to true requires the queue to be transactional.
