Client and server channels based on WebsocketSharp implementation of web sockets

### Describe your question
A clear and concise description of what you want to know.

I am implementing a standalone broker to be hosted in standalone Windows service process, and not hosted in IIS (not ASP.Net nor ASP.Net Core).

I need to support 3 classes of client nodes:
* .Net Framework / C# implementation
* PWA hosted inside CEF browser embedded into .Net Fraemwork / C# application - so i have a choice between WebSocket and Tcp channels for clients
* PWA hosted by the browser - no more choice of Tcp client, only WebSocket.

I need to support mixed clients (like browser based front-end node connecting to a .Net based self-hosted back-end node),

Let me summarize - no IIS anywhere in any configurations / scenarios. But need to support calls from the browser-based clients.

### Which project is your question related to?

- Server

What should I override / overload / inject to support WesocketSharp-based Web sockets implementation of the client and server channels?

Thanks.
