Unity .net / nodejs problem

[blenderino100]

Hello! I would like to ask for help. What could be the problem?

Unity Client

using UnityEngine;
using SocketIOClient;

public class NetworkClient : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        var client = new SocketIO("http://localhost:3000/");
        client.On("connection", socket => {
            Debug.Log("test");
        });
    }
    // Update is called once per frame
    void Update()
    {


    }
}

NodeJS server

const io = new Server();

io.on("connection", (socket) => {
  console.log("test 2")
});

io.listen(3000);

I start both and for some reason there is no communication. What am I wrong about? Thank you in advance for your answer. Have a nice day!

Is there a line of code missing?

    void Start()
    {
        var client = new SocketIO("http://localhost:3000/");
        client.On("connection", socket => {
            Debug.Log("test");
        });
        await client.ConnectAsync();
        // ^^^^^^^^^^^^^^^
    }

Hi @blenderino100 , how did you get SocketIO working with Unity? I think our connection is not working since we are using an older version (2.x) of SocketIO, but the top plugin on NuGet by HeroWong's DLLs did not play nice with Unity. I do not think it is a problem with the code, we get a response from Unity saying that the connection is not open.

This is what we tried to install the DLLs from that didn't work: https://www.nuget.org/packages/SocketIOClient/

So here is what we actually used: https://www.nuget.org/packages/SocketIOClient.NetFx/

@jcortezzo Hi I create a new 2.0 .net and installed SocketIOClient build > after in console > dotnet publish and copied the new files to a unity project it works without errors
