Remarks

Any EventHubReceiver created from this instance will inherit this value by default. Changes to this value will not be propagate to already created receiver, but will be used by new EventHubReceiver created after the change. Also setting this property to non-zero will set PrefetchSizeInBytes to null. Note that setting the count too low will affect the effective performance of the event hub receive call.
