Is there a WebSockets based implementation for Firebase (third-party or from Google) for C#.NET?
Almost four years ago, Michael Lehenbauer said:
"The wire protocol used within the WebSocket isn't documented or stable, and the guts of the client code are actually pretty gnarly. We're hoping to release a spec in the future so people can write more clients, but it's changing too frequently right now." (https://stackoverflow.com/a/10729948/4490069)
Today, the Web Sockets standards seem to be at a standstill and not, "changing quickly," the working group has had no activity, and the latest update to "The WebSocket API W3C Candidate Recommendation 20 September 2012" is October 2015 (https://www.w3.org/TR/websockets/).
As Michael states, the demand was high enough a few years ago to keep this on the Firebase team's roadmap, but development hasn't occurred due to unstable standards. The standards have become stable enough for Microsoft to develop a WebSockets implementation for Azure called SignalR. If nobody knows if Firebase is still pursuing an official .NET WebSockets implementation, has the community upgraded third-party Firebase support with WebSockets or HTTP keep-alive?
