Within a system, components communicate with each other through methods, services, etc. But what to do when a database connection times out, or the famous NullReference exception occurs? We log the error, but how do we offer call again to our system? Can we do this automated? During this session you’ll learn how to use messaging to solve the mentioned issues. How you can build more reliable, measurable and more robust software. You’ll also learn how to do this with both WCF and NServiceBus.
