MsmqBindingBase::TimeToLive Property
Gets or sets the interval of time that indicates how long the messages processed by this binding can be in the queue before they expire.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
The TimeToLive property is set to ensure that time-sensitive messages do not become stale before they are processed by the receiving applications. A message in a queue that is not accessed by the receiving application within the time interval specified is expired. Expired messages are sent to a special queue called the dead-letter queue. The location of the dead-letter queue is set with the DeadLetterQueue property or to the appropriate default, based on assurances.
