It would be ideal to light up Azure Service Bus as a means for import or export of data. This is great for recurring integrations inbound or outbound. We build this on every implementation however it would make a great addition to the standard product.
Using data entities we would enable change tracking on them and export out the changes similar to EntityStore. However this would be to an Azure Service Bus Queue or Topic. Also if this framework had public APIs in X++ then extension packages could make use of this as well.
Data entity is serialized in to JSON and integrated outbound. There would need to be a means to show the JSON data contract for a given data entity so that developers could generate the proper schema for inbound scenarios.
