Net maui cannot get information from WebSocket api

[zor038]

Type of issue

Other (describe below)

Description

I have a WebSocket application that I used in C# console before. I had no problems with it working in console, but I want to convert it to a multimedia project with netmau. Android emulator does not work on my computer. That's why I do my tests in Windows emulator.

When I check with brekboint in the code I shared below, it gets stuck when it reaches WebSocketReceiveResult result = await webSocket.ReceiveAsync(new ArraySegment(buffer), CancellationToken.None); I can't get any response. I don't know if I'm starting the application incorrectly or if there's a part I need to add.

My codes are as follows, I would be glad if you could guide me :(

`using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.WebSockets;
using System.Text;
using System.Threading.Tasks;

namespace MauiApp1.Model
{
public static class WebSocket
{
public static string checker = Ayarlar.ComputeSha256Hash(Ayarlar.APIKEY + Ayarlar.hostname + "/ws");
public static ClientWebSocket webSocket = new ClientWebSocket();
public static DateTime senddate = DateTime.Now;
public static async Task ConnectToWebsocket()
{
try
{
webSocket.Options.SetRequestHeader("APIKEY", Ayarlar.APIKEY);
webSocket.Options.SetRequestHeader("Authorization", Ayarlar.HASH);
webSocket.Options.SetRequestHeader("Checker", checker);
await webSocket.ConnectAsync(new Uri(Ayarlar.websocketurl), CancellationToken.None);

        await Task.WhenAll(Receive(webSocket), Send(webSocket));
    }
    catch (Exception ex)
    {
    }
}
private static async Task Receive(ClientWebSocket webSocket)
{
    byte[] buffer = new byte[1024];
    while (webSocket.State == System.Net.WebSockets.WebSocketState.Open)
    {
        try
        {
            WebSocketReceiveResult result = await webSocket.ReceiveAsync(new ArraySegment<byte>(buffer), CancellationToken.None);

            string a = System.Text.Encoding.UTF8.GetString(buffer, 0, result.Count);
            WebsocketData model = new WebsocketData();
            model = JsonConvert.DeserializeObject<WebsocketData>(a);
            if (model != null && model.Type == "D")
            {
                Depth depthmodel = JsonConvert.DeserializeObject<Depth>(JsonConvert.SerializeObject(model.Content));

                Console.WriteLine(JsonConvert.SerializeObject(depthmodel));

            }
            else if (model != null && model.Type == "T")
            {
                Tick tickmodel = JsonConvert.DeserializeObject<Tick>(JsonConvert.SerializeObject(model.Content));

                Console.WriteLine(JsonConvert.SerializeObject(tickmodel));

            }

            //Console.WriteLine(a);
        }
        catch (Exception ex)
        {
        }
    }
    if (webSocket.State != System.Net.WebSockets.WebSocketState.Open)
    {
        ConnectToWebsocket();
    }
}

private static async Task Send(ClientWebSocket webSocket)
{

    while (webSocket.State == System.Net.WebSockets.WebSocketState.Open)
    {

        if (senddate < DateTime.Now)
        {
            senddate = DateTime.Now.AddMinutes(15);
            string message = "{\"Type\":\"H\",\"Token\":\"" + Ayarlar.HASH + "\"}";

            var encoded = Encoding.UTF8.GetBytes(message);
            var buffer = new ArraySegment<Byte>(encoded, 0, encoded.Length);
            await webSocket.SendAsync(buffer, WebSocketMessageType.Text, true, CancellationToken.None);

        }
    }
}

}`

The code I use to start the code is as follows

` public MainPage()
{
InitializeComponent();

WebSocket.ConnectToWebsocket();
}`

I would be very glad if you could support me on this subject. Thank you in advance
