MassTransit temporary queue pile up

Question

(See also MassTransit AzureServiceBus generated queues)

I'm configuring a bus with the following using MassTransit 4.0 with AzureServiceBus for transport:

Bus.Factory.CreateUsingAzureServiceBus(cfg =>
{
    IServiceBusHost host = cfg.Host(
        BusHostUri,
        hostCfg =>
        {
            hostCfg.TokenProvider = TokenProvider.CreateSharedAccessSignatureTokenProvider(
                KeyName,
                SharedAccessKey);
        });

    cfg.ReceiveEndpoint(host, QueueName, e =>
    {
        e.Consumer<ValueEnteredConsumer>();
    });
});

When run it creates:

• A queue matching QueueName
• A topic matching the message type from the consumer
• A subscription under that topic matching QueueName and forwarding messages to that queue

• A queue named something in the form of:

  {machine}_{application}_bus_{26 random letters}

The first three seem fine. However for that last item, the temporary queue I believe, each restart triggers a newly created queue. From Service Bus Explorer it appears that the queue has AutoDeleteOnIdle set 427 days.

What do I need to do to allow/require the temporary queues to be deleted within a more reasonable time window (e.g., 10 days)? And, if possible, to have the application that created it also delete it during shutdown.
