4 years ago Created a new console app using c#, .net core 2.1, & WebSocketServer (installed via nuget). Same result, able to connect but then there is an immediate disconnect. Also tried 2.2, 3.0, & 3.1.
It never displays "NewSessionConnected".
using SuperWebSocket;
using System;
namespace ConsoleApp1
{
class Program
{
private static WebSocketServer wsServer;
static void Main(string[] args)
{
Console.WriteLine("Hello World!");
wsServer = new WebSocketServer();
int port = 8088;
wsServer.Setup(port);
wsServer.NewSessionConnected += WsServer_NewSessionConnected;
wsServer.NewMessageReceived += WsServer_NewMessageReceived;
wsServer.NewDataReceived += WsServer_NewDataReceived;
wsServer.SessionClosed += WsServer_SessionClosed;
wsServer.Start();
Console.WriteLine("Server is running on port " + port + ". Press ENTER to exit....");
Console.ReadKey();
}
private static void WsServer_SessionClosed(WebSocketSession session, SuperSocket.SocketBase.CloseReason value)
{
Console.WriteLine("SessionClosed");
}
private static void WsServer_NewDataReceived(WebSocketSession session, byte[] value)
{
Console.WriteLine("NewDataReceived");
}
private static void WsServer_NewMessageReceived(WebSocketSession session, string value)
{
Console.WriteLine("NewMessageReceived: " + value);
if (value == "Hello server")
{
session.Send("Hello client");
}
}
private static void WsServer_NewSessionConnected(WebSocketSession session)
{
Console.WriteLine("NewSessionConnected");
}
}
}

After viewing: https://www.youtube.com/watch?v=JbXurSfeceY Implemented the technique there (see its comment for the code) but using SuperSocket .WebSocket instead of SuperWebSocket.
Added to a pre-existing REST API using C# .net core 2.1, by adding to the Program.cs file.
I can see with my debug messages the server is starting & I am able to telnet to the port from a different computer.
I tried testing using websocket.org/echo.html from another pc. I can see via wireshark a response "HTTP/1.1 101 Switching Protocols", however ... via the testing website it only says DISCONNECT & I'm unable to test sending a message. I'm not getting any exceptions.
Packages installed via nuget with Visual Studio 2019. SuperSocket.WebSocket (1.6.6.1) SuperSocket.Engine (1.6.6.1)
1) Is there another package I need to install? 2) Does this work with .net core? 3) Is there an easy way to see if the websocketserver is functioning as expected? 4) How to increase debugging messages from SuperSocket?
