Two Way Data Sync Between Web API Server and Desktop App

[maroonedsia]

Hi, I'm very new to reactive programming, and I have some naïve questions, please.

Imagine I have a desktop app on WFP, that interacts with my web API server on ASP.NET core. Are reactive extensions capable of performing 2-way automatic updates between the server and client? e.g.

• If there are updates on the server, push the changes automatically to the client app, without needing the client app to poll the server repeatedly (something like the way Web Sockets / SignalR works).
• If there are updates on the client, push the changes to the server automatically (well, this one can be performed by sending automated POST requests to the server, but I want to see if reactive extensions have other elegant mechanisms for this)

If any of these are possible, could you please point me to the related docs? Thanks a lot! 😎
