Raw WebSocket

var ws = new ClientWebSocket(); await ws.ConnectAsync(new Uri(url), CancellationToken.None); // handshake and message parsing required

Using Ecng

var socket = new WebSocketClient( url, state => Console.WriteLine($"State: {state}"), ex => Console.WriteLine(ex), (c, msg, ct) => { Console.WriteLine(msg.Text); return ValueTask.CompletedTask; }, Console.WriteLine, Console.Error.WriteLine, Console.WriteLine); await socket.ConnectAsync(); socket.Send(new { hello = "world" });
