概述：一款名为WPFUI的轻量级开源库，为WPF应用程序提供现代化界面。支持MVVM和Microsoft.Extensions.DependencyInjection，简单上手。无第三方依赖，内置两套皮肤，可自定义样式。适用于一般应用场景，不受MVVM框架限制。通过简单的引用和配置，快速构建现代化WPF应用，提升用户体验

最近要做个小工具软件，发现以前用的WPF界面有点老了，所以在网上找下，发现一个用起来还可以的WPFUI库，MVVM也支持得很好，同时支持微软官方的依赖注入框架Microsoft.Extensions.DependencyInjection。

先来看看运行效果：

使用方法也比较简单。

1、引用库：

2、App.xaml引入资源

3、App.xaml.cs注册相关的Page、ViewModel、Service

public partial class App
    {
        // The.NET Generic Host provides dependency injection, configuration, logging, and other services.

        private static readonly IHost _host = Host
            .CreateDefaultBuilder()
            .ConfigureAppConfiguration(c => { c.SetBasePath(Path.GetDirectoryName(Assembly.GetEntryAssembly()!.Location)); })
            .ConfigureServices((context, services) =>
            {
                services.AddHostedService();

                services.AddSingleton();
                services.AddSingleton();
                services.AddSingleton();
                services.AddSingleton();
                services.AddSingleton();

                services.AddSingleton();
                services.AddSingleton();
                services.AddSingleton();
                services.AddSingleton();
                services.AddSingleton();
                services.AddSingleton();
            }).Build();

        /// Gets registered service.
        /// 
        /// Type of the service to get.
        /// Instance of the service or .
        public static T GetService()
            where T : class
        {
            return _host.Services.GetService(typeof(T)) as T;
        }

        /// 
        /// Occurs when the application is loading.
        /// 
        private void OnStartup(object sender, StartupEventArgs e)
        {
            _host.Start();
            Wpf.Ui.Appearance.Theme.Apply(Wpf.Ui.Appearance.ThemeType.Dark);
        }

        /// 
        /// Occurs when the application is closing.
        /// 
        private async void OnExit(object sender, ExitEventArgs e)
        {
            await _host.StopAsync();

            _host.Dispose();
        }

        /// 
        /// Occurs when an exception is thrown by an application but not handled.
