Declare passive queue but also get the queue object

I’m migrating to net 5.0 and moving away from the 2.x version of this lib. Is there a way to replace these calls with something similar?

 // passive, throws exception if queue not found.
_queue = _bus.Bus.QueueDeclare(_config.QueueInfo.Name, true);

I’m asking because I’ve found that there is QueueDeclarePassive, but it has a void return type.

// create queue 
  _queue = _bus.Bus.QueueDeclare(
      name: _config.QueueInfo.Name,
      passive: false,
      durable: false,
      exclusive: false,
      autoDelete: _config.QueueInfo.AutoDelete,
      perQueueMessageTtl: ttl,
      maxLength: maxLen,
      maxLengthBytes: maxMem);

How can I set the TTL and maxLength?

I too was looking for a way to declare a queue passively.

This workaround helped me.

await _bus.Advanced.QueueDeclarePassiveAsync("QueueName", stoppingToken);
var queue = new EasyNetQ.Topology.Queue("QueueName");

Of course, it isn’t really convenient. It seems the breaking change goes back to this PR https://github.com/EasyNetQ/EasyNetQ/pull/921

Hi @Sam-Lin-MillersLab,

QueueDeclarePassiveAsync only ensures that a queue with the provided name exists, therefore we still cannot construct a proper queue object, because do not know anything about the queue except its name.

#1678 only helps to fill in queue arguments.
