1. 本文背景
使用简单动画实现抽屉式菜单
2. 代码实现
使用 .NET CORE 3.1 创建名为 “AnimatedColorfulMenu” 的WPF模板项目，添加1个Nuget库：MaterialDesignThemes，版本为最新预览版3.1.0-ci948。
解决方案主要文件目录组织结构：
AnimatedColorfulMenu
App.xaml
MainWindow.xaml
2.1 引入样式
文件【App.xaml】，在 StartupUri 中设置启动的视图【MainWindow.xaml】，并在【Application.Resources】节点增加 MaterialDesignThemes库的样式文件：
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.Blue.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Indigo.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
2.2 演示窗体布局
文件【MainWindow.xaml】，代码不多，主要看左侧菜单，启动时，菜单在显示窗体左侧-150位置；点击展开菜单，使用简单的动画，慢慢呈现在显示窗体左侧，源码如下：
