C#: Update Label Text On Windows Forms From Console Application

Question

I'm trying to update a the text inside a label in a Windows Forms launched from a Console Application, as an example I've created this code.

    static void Main(string[] args)
    {
        Form form = new Form();
        Label label = new Label();

        label.Text = "hi";
        form.Controls.Add(label);
        form.ShowDialog();

        Thread.Sleep(2000);

        label.Text = "bye";
        label.Invalidate();
        label.Update();
        //Refresh Doesn't work either
        //_BuyLabel.Refresh();
        Application.DoEvents();
    }

I've done my research but my knowledge of Windows Forms is quite limited, the libraries for this are already included and are not a problem.

What else do I need to do to update the text or any other Control feature?

Try this:

class Program
{
    private static Form form = new Form();
    private static Label label = new Label();

    static void Main(string[] args)
    {
        label.Text = "hi";
        form.Controls.Add(label);

        form.Load += Form_Load; // Add handle to load event of form

        form.ShowDialog();
        Application.DoEvents();

    }

    private async static void Form_Load(object sender, EventArgs e)
    {
        await Task.Run(() =>             // Run async Task for change label.Text
        {
            Thread.Sleep(2000);
            if (label.InvokeRequired)
            {
                label.Invoke(new Action(() =>
                {
                    label.Text = "bye";
                    label.Invalidate();
                    label.Update();
                }));
            }
        });
    }
}

I run this on my pc, and work.
