The .NET services bus was developed with solving the connectivity issue of web services, and as a general way of relaying messages to services. But controlling a messaging junction in the cloud has the potential for much more than messages relay. The services bus can act as a sophisticated interceptor, adding valuable aspects to your application. The first such aspects are routing and queuing. You can install a router to send messages to multiple subscribers or act as a load balancer. You can have the services bus queue up your client calls until the service is ready to process them. You can combine routers and queues, and have queues and routers subscribe to routers, enabling application features that would be very difficult without the services bus. This session presents the new capabilities and the new design patterns and pitfalls. You will also see some advanced WCF programming techniques, original helper classes, productivity-enhancing utilities and tools.
