在開發浩辰Cad2020時候，加載wpf面板后顯示為空，但是加載form.control面板卻可以

幫我看下是我的代碼有問題嗎

public static PaletteSet palette1 = new PaletteSet("智能平臺 beta_1.0.0", new Guid("A1333878-b1d8-4d40-99f6-6e6224d43212"));
        internal static MainWindow1 panels1 = new MainWindow1();
        internal static MainWindow2 panels2 = new MainWindow2();
        internal static MainControl1 panels3 = new MainControl1();


        [CommandMethod("BlueSword", CommandFlags.Session)]
        public void showPaleter()
        {
            palette1.Size = new System.Drawing.Size(350, 900);
            palette1.MinimumSize = new System.Drawing.Size(250, 600);
            palette1.Location = new System.Drawing.Point(250, 50);
            palette1.DockEnabled = DockSides.Right;
            palette1.Dock = DockSides.Right;
            palette1.Opacity = 60;
  palette1.AddVisual("Git測試", panels2);
            palette1.Add("Git測試", panels3);
            palette1.Size = new System.Drawing.Size(150, 900);
            palette1.Visible = true;
        }
