没有xaml的WPF

出于强迫症，我查了一下文档弄明白了WPF脱离xaml应该怎么搞。当然其实本质是为了MaxScript里使用做准备。

using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;

namespace SimpleWPF
{
    public static class Program
    {
        [STAThread]
        public static void Main()
        {
            Window theWindow = new Window();
            theWindow.Height = 600;
            theWindow.Width = 800;
            
            Button theButton = new Button();
            theButton.Content = "Button";
            theButton.Click += delegate(object sender, RoutedEventArgs e) { MessageBox.Show("Click"); };

            theWindow.Content = theButton;
            Application theApplication = new Application();
            theApplication.Run(theWindow);
        }
    }
}
