This document defines a mechanism to establish multiplexed, platform-level information flow between the tenant scopes of different, multitenant platform-as-a-service (PaaS) or software-as-a-service (SaaS) systems. In particular, this specification introduces the concept of a tenant-bridging “channel” that is established as a communication link between the tenants of two cooperating platforms. While the mechanism defined here is quite simple, the solved problem requires quite a bit of context setting:

What are we solving?

The "cooperating platforms" are commonly from different cloud service vendors and are addressing different customer scenarios. Examples might be enterprise resource planning (ERP) on one side and general-purpose application hosting on the other. A scenario to enable might be for the ERP system to be easily extensible with event-driven serverless functionality hosted on the other platform.

This JSON.Net converter handles F# discriminated unions with more "idiomatic" JSON than what is generated by the current version of JSON .NET. Option types and single case DUs are transparently handled, and tuple-style properties are used rather than array notation.
