新学WPF，准备把玻璃窗效果封装成方法，以后需要可以直接调用但是遇到了点问题。直接发代码

封装方法：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Interop;
using System.Windows.Media;
using Microsoft.WindowsAPICodePack.Shell;
using Dedom;

namespace Dedom
{
  public static  class MainWindows
    {
      public static void ExtendAeroGlass(Window window)
        {
            try
            {
                // 为WPF程序获取窗口句柄
                IntPtr mainWindowPtr = new WindowInteropHelper(window).Handle;
                HwndSource mainWindowSrc = HwndSource.FromHwnd(mainWindowPtr);
                mainWindowSrc.CompositionTarget.BackgroundColor = Colors.Transparent;

                // 设置Margins
                MARGINS margins = new MARGINS();

                // 扩展Aero Glass
                margins.cxLeftWidth = -1;
                margins.cxRightWidth = -1;
                margins.cyTopHeight = -1;
                margins.cyBottomHeight = -1;

                int hr = DwmExtendFrameIntoClientArea(mainWindowSrc.Handle, ref margins);
                if (hr < 0)
                {
                    MessageBox.Show("DwmExtendFrameIntoClientArea Failed");
                }
            }
            catch (DllNotFoundException)
            {
                Application.Current.MainWindow.Background = Brushes.White;
            }
        }

        [StructLayout(LayoutKind.Sequential)]
        public struct MARGINS
        {
            public int cxLeftWidth;
            public int cxRightWidth;
            public int cyTopHeight;
            public int cyBottomHeight;
        };

        [DllImport("DwmApi.dll")]
        public static extern int DwmExtendFrameIntoClientArea(
            IntPtr hwnd,
            ref MARGINS pMarInset);
    }
}

窗口调用

   public MainWindow()
        {
            InitializeComponent();
            ////Window1 w1 = new Window1();
            //////w1.Owner = this;
            //w1.Show();
           
            this.Activate();
            this.WindowState = WindowState.Normal;
           
            his.Background = Brushes.Transparent;
            MainWindows.ExtendAeroGlass(this);
            }

错误提示：

无法创建在程序集“Dedom, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null”中定义的“Window1”的实例。 调用的目标发生了异常。  标记文件中“Dedom;component/Window2.xaml”行1位置9处的错误

如果在窗口调用的时候换成按键调用就没有问题，但是我想做成窗体加载就调用求高手帮忙！
