Weird connecting issue

[FaNim21]

Hello i want to ask about connecting to obs

bool isConnected = await Client.ConnectAsync(true, CurrentChosen!.Password, "localhost", CurrentChosen.Port);
Client.ConnectionClosed += (x, args) => { MessageBox.Show("Lost connection"); };
if (isConnected)
{
    try
    {
        //await Task.Delay(1000);

        await Client.SetCurrentSceneCollection(CurrentChosen.SceneCollection);
        await Client.SetCurrentProgramScene(CurrentChosen.Scene);

        MessageBox.Show("Connected to obs succesfully");
    }
    catch (Exception ex)
    {
        MessageBox.Show($"Error: {ex.Message} - {ex.StackTrace}");
        Disconnect();
        return;
    }
}

because I am experiencing issues with the isConnected variable. It should be true if it is really connected to OBS, but without setting a delay like 500-1000ms, when I attempt to set the current scene collection, I get an error stating that OBS is not connected. It seems like there is an issue with the waiting process because my variable is true, but I still receive an error indicating that it is not connected. Maybe I've done something wrong?

The behavior you are seeing is as designed. The fact that ConnectAsync returns true merely means that a WebSockets connection to OBS Studio could be established. If you don't use authentication, you can immediately start sending commands to OBS Studio. If you are using authentication, you have to wait for the authentication process to complete. (The ConnectionState property has the value Authenticating as long as the authentication hasn't completed yet.) After the authentication is done, the ConnectionState either is Disconnected (the authentication failed and you are disconnected from OBS Studio) or it is Authenticated (and you can start sending commands). You can achieve this by simply waiting after calling ConnectAsync, but there are a more elegant solutions.

You can subscribe to the PropertyChanged event and see whether the ConnectionState property has the desired value (e.g. Connected), and then continue. Or you can wait for the ConnectionState to become Connected and then continue. This will prevent you having to wait an arbitrary amount of time. In essence, you wait for at most a certain amount of milliseconds, or until the authentication has happened; whichever occurs first.

An example:

            var client = new ObsClient();
            TaskCompletionSource<bool> tcs = new();
            client.PropertyChanged += (sender, eventArgs) =>
            {
                if (eventArgs.PropertyName == "ConnectionState" && client.ConnectionState == ConnectionState.Connected)
                {
                    tcs.TrySetResult(true);
                }
            };
            var isAuthenticated = false;
            var isConnected = await client.ConnectAsync(true, "P@ssw0rd");
            if (isConnected)
            {
                using CancellationTokenSource cts = new(1000); // Wait at most 1000ms for the authentication to complete.
                using var ctr = cts.Token.Register(() => tcs.TrySetCanceled(), false);
                try
                {
                    isAuthenticated = await tcs.Task;
                }
                catch (TaskCanceledException)
                {
                    // Authentication timed out or is invalid
                }
                finally
                {
                    _ = ctr.Unregister();
                }
            }

            await Console.Out.WriteLineAsync($"Connected: {isConnected}, Authenticated: {isAuthenticated}");
