I tried to compare query declaration code in logtain and WCF example and
haven't found significant differences.


Ok. This is code from WCF service model implementation
(RabbitMQInputChannel.cs):

	//Create a queue for messages destined to this service, bind it to
the service URI routing key
            
            string queue = model.QueueDeclare(ticket);
            model.QueueBind(ticket, queue, base.LocalAddress.Uri.Host,
base.LocalAddress.Uri.PathAndQuery, false, null);

            //Listen to the queue
            messageQueue = new QueueingBasicConsumer(model);
            model.BasicConsume(ticket, queue, null, messageQueue);


and this code is from logtail:

using (IModel ch = conn.CreateModel()) {
                        ushort ticket = ch.AccessRequest("/data");

                        Subscription sub;
                        if (exchange == "") {
                            sub = new Subscription(ch, ticket, routingKey);
                        } else {
                            sub = new Subscription(ch, ticket, exchange,
exchangeType, routingKey);
                        }

And Subscribtion implamentation code (Subscription.cs) for query creating:

    m_queueName = m_model.QueueDeclare(ticket);



Maybe I missed something, but I fell the same, that something with query
declaration is wrong.
