How to use (server)

Install this nuget package (and this one)

using Tesses.RPC;
using Tesses.WebServer;

    Number

                await e.StartEasyWebSocketConnectionAsync(ews);
            }
        );
        svr.StartServer(4222);
    }
}

Can I implement a client in other languages

Yes this program uses json and here is some documentation on json structure (uses text in WebSocket but I designed this to be usable with other means of transport (as long as sending and receiving are on seperate threads))
