WebSocket Event Listener

WebSocketListener can be used in many ways. If you are more familiar with event driven approaches, you can create a very simple WebSocketEventListener class that allows you to subscribe to events, rather than doing asynchronous awaits. For example, a echo service would look like this:

using (var server = new WebSocketEventListener(new IPEndPoint(IPAddress.Any, 8009)))
{
    server.OnConnect += (ws)=> Console.WriteLine("Connection from " + ws.RemoteEndpoint);
    server.OnDisconnect += (ws) => Console.WriteLine("Disconnection from " + ws.RemoteEndpoint);
    server.OnError += (ws, ex) => Console.WriteLine("Error: " + ex.Message);
    server.OnMessage += (ws, msg) =>
        {
            Console.WriteLine("Message from [" + ws.RemoteEndpoint + "]: " + msg);
            ws.WriteStringAsync(msg, CancellationToken.None).Wait();
        };

    server.Start();

    ...
}

The WebSocketEventListener class can be found here.
