title: What does "IsTransactional" in NServiceBus mean?
body: <p>I am creating a web application that is going to <em>send</em> messages using NServiceBus, and also write to a database. I want this to be an atomic operation, i.e. a transaction, so I wrap the code in a using new TransactionScope() statement.</p>
  
  <p>When configuring NServiceBus you can call the IsTransactional-method. When do I pass 'false' to this method, and when is 'true' appropriate?</p>
