In the .NET version (2.4.1) of RabbitMQ the RabbitMQ.Client.MessagePatterns.SimpleRpcClient has a Call() method with these signatures:

    public virtual object[] Call(params object[] args);
    public virtual byte[] Call(byte[] body);
    public virtual byte[] Call(IBasicProperties requestProperties, byte[] body, out IBasicProperties replyProperties);

The problem:

With various attempts, the method still continues to not block where I expect it to, so it's unable ever handle the response.

The Question:

Am I missing something obvious in the setup of the SimpleRpcClient, or earlier with the IModel, IConnection, or even PublicationAddress?

More Info:

I've also tried various paramater configurations of the QueueDeclare() method too with no luck.

string QueueDeclare(string queue, bool durable, bool exclusive, bool autoDelete, IDictionary arguments);

Some more reference code of my setup of these:

IConnection conn = new ConnectionFactory{Address = "127.0.0.1"}.CreateConnection());
using (IModel ch = conn.CreateModel())
{
     var client = new SimpleRpcClient(ch, queueName);
     var queueName = ch.QueueDeclare("t.qid", true, true, true, null);

     ch.QueueBind(queueName, "exch", "", null);

     //HERE: does not block?
     var replyMessageBytes = client.Call(prop, msgToSend, out replyProp);
}

Looking elsewhere:

Or is it likely there's an issue in my "server side" code? With and without the use of BasicAck() it appears the client has already continued execution.
