hi every one please any one tell me how can i create connection with websocket in our c# application.
Actually i want to implement Card payment system in our EPOS application.
so i need to create connection with websocket but i don't know how can i do it.

i also found one link of webscoket in c#
but i cannot understand it clearly.

This is the Websocket Connection URI:

wss://sc327v760000.test.connect.paymentsense.cloud/pac?token=d125c1d5-9062-4ec4-b4c0-6cb0a2490e95&api-version=v1&software-house-id=SC327V76&installer-id=SC327V76

I need to maintain that connection in our EPoS

in a background thread
i also get some information related to websocket but i dont know how can i implement it in our application.




"
whenever something arrives on that message, or you want to post a message

you just pass it on to the websocket client

ws.Send ("BALUS");

{
  "jsonrpc": "2.0",
  "method": "connectedTerminals",
  "id": 1
}

i'm a biggner please i wait for some one help

What I have tried:

i have found this code but i dont know how can i implete this in our application

using System;
using WebSocketSharp;

namespace Example
{
  public class Program

    {
      using (var ws = new WebSocket ("ws://dragonsnest.far/Laputa")) {
        ws.OnMessage += (sender, e) =>
            Console.WriteLine ("Laputa says: " + e.Data);
