title: What tools do you use to implement SOA/Messaging?
body: <p><a href="http://www.nservicebus.com/" rel="nofollow noreferrer">NServiceBus</a> and <a href="http://code.google.com/p/masstransit/" rel="nofollow noreferrer">MassTransit</a> are two tools that can be used to implement messaging with MSMQ and other message queues.</p>
  
  <p>I find that once you start using messaging to have applications talk to each other, you don't really want to go back to the old RPC style.</p>
  
  <p>My question is, what other tools are out there? What tools do you use?</p>
