in working with the samples I am using the following test consumer snippet ...<br><br>&lt;snip&gt;<br>ServiceHost dispatcherHost = new ServiceHost(typeof(DispatcherService), new Uri(&quot;soap.amqp:///&quot;));<br>dispatcherHost.AddServiceEndpoint(typeof(IDispatcherService), new RabbitMQBinding(new Uri(&quot;amqp://localhost:5672/&quot;), Protocols.AMQP_0_8), &quot;soap.amqp://localhost/dispatcher&quot;);<br>
&lt;/snip&gt;<br><br>when the RabbitMQBinding is hit in the RabbitMQ.Service model I get the following nasty gram...<br><br>RabbitMQ.Client.Exceptions.OperationInterruptedException was unhandled by user code<br>  Message=&quot;The AMQP operation was interrupted: AMQP close-reason, initiated by Peer, code=404, text=\&quot;NOT_FOUND - no exchange &#39;localhost&#39; in vhost &#39;/&#39;\&quot;, classId=50, methodId=20, cause=&quot;<br>
