Implementing Dynamics 365 Service Bus Listener using Azure Function

One of the built-in triggers for Azure Function App is Service Bus (ASB) queue trigger, which makes Azure Function a listener for ASB events.
While Azure Service Bus provides a robust decoupling mechanism, the receiving side has to poll for messages or implement a listener. 

This trigger makes Azure Functions an ideal implementation component for Inbound Asynchronous Integration with Microsoft Dynamics 365,
one that allows you to write custom code, but releases you from explicitly writing a listener.
An Inbound Asynchronous Integration pattern describes scenarios where a business event occurs in an external application and must be reflected into Dynamics 365.
Processing of the event in Dynamics 365 does not occur immediately and sometimes no response is required from Dynamics 365 side (one way).

In this post I’ll walkthrough the process of setting an Azure Function as an ASB one-way listener which posts incoming messages into Dynamics 365.
