Vous ne pouvez ajouter un Image donc vous devez créer que:

RectangleF rectF = new RectangleF(0, 0, 40, 40); 
    Bitmap bitmap = new Bitmap(40, 40, System.Drawing.Imaging.PixelFormat.Format24bppRgb); 
    Graphics g = Graphics.FromImage(bitmap); 
    g.FillRectangle(System.Drawing.Brushes.White, 0, 0, 40, 40); 
    g.DrawString("5", new Font("Arial", 25), System.Drawing.Brushes.Black, new PointF(0, 0)); 

    IntPtr hBitmap = bitmap.GetHbitmap(); 

    ImageSource wpfBitmap = 
     Imaging.CreateBitmapSourceFromHBitmap(
      hBitmap, IntPtr.Zero, Int32Rect.Empty, 
      BitmapSizeOptions.FromEmptyOptions()); 

    TaskbarItemInfo.Overlay = wpfBitmap;
