AppFx.ServiceBus Client Framework

Framework to simplify hybrid messaging implementation with Windows Azure Service Bus

Connected Systems Consulting Ltd

Why do we need this?We love Windows Azure Service Bus but in real world projects there are still challenges:

• IIS hosted WCF didn’t work that great• Handle different types of message• Different message formats eg. XML or JSON• There’s lots of plumbing code to write• Where do you host receive code?• What about Message Factory refreshing• Need some standards to ensure interoperability• Lots of different message exchange patterns

– Scatter Gather– RPC– One way
