title: NServiceBus vs Windows ServiceBus
body: <p>Would someone be able to shed some light on the differences between the newly release Windows ServiceBus (on premise, not Azure) and NServiceBus?</p>
  
  <p>Looking for a detailed answer what the windows SB may be missing as I'm familiar what NSErviceBus can do:</p>
  
  <ol>
  <li>Is it a real service bus and not just a message broker that uses queues?</li>
  <li>Can it support message polymorphism? (Messages subclassing other
  messages and handlers supporting this hierarchy</li>
  <li>Long running processes and correlation</li>
  <li>Scale out</li>
  </ol>
