This document introduces AppFx.ServiceBus, a framework that simplifies implementing hybrid messaging with Windows Azure Service Bus. It discusses the challenges with existing solutions, such as needing to write a lot of plumbing code. AppFx.ServiceBus aims to provide a simplified development experience, support common messaging patterns, and establish standards for interoperability. Key use cases include connecting old versions of BizTalk to Azure Service Bus or doing lightweight queued messaging. The document demonstrates AppFx.ServiceBus with a scenario of integrating an on-premise WCF service and includes information on features and where to find more details.

Framework to simplify hybrid messaging
implementation with Windows Azure Service Bus

5. 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
