using System; 
using System.Threading.Tasks; 
using System.Windows.Forms; 

class FlickerForm 
{ 
    public static void Execute() 
    { 
    var button = new Button { Width = 200, Height = 30, Text = "Test" }; 
    var button2 = new Button { Width = 200, Height = 30, Top = 30, Text = "Test2" }; 
    var form = new Form { Width = 800, Height = 600, Controls = { button, button2 } }; 

    form.Load += async (_s, _e) => await Task.WhenAll 
    (
     Flicker(button, TimeSpan.FromSeconds(2)), 
     Flicker(button2, TimeSpan.FromSeconds(3)) 
    ); 

    Application.Run(form); 
    } 

    static async Task Flicker<T>(T target, TimeSpan period) where T:Control 
    { 
    for (var isWhite = false; ; isWhite = !isWhite) 
    { 
     target.BackColor = isWhite ? System.Drawing.Color.White : System.Drawing.Color.Black; 
     await Task.Delay(period); 
    } 
    } 
}
