1.实现效果
自定义菜单切换动画
2.业务场景
菜单切换动画
3.编码实现
3.1 添加Nuget库
使用 .Net Core 3.1 创建名为“CustomMenu”的WPF解决方案，添加两个Nuget库：MaterialDesignThemes和MaterialDesignColors。
MaterialDesign控件库
3.2 工程结构
只修改了App.xaml（添加MD控件样式）和MainWindow.xaml（主窗口实现效果）。
3.3 App.xaml引入MD控件样式
<Application x:Class="CustomMenu.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:CustomMenu"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Dark.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
</ResourceDictionary.MergedDictionaries>
<!--PRIMARY-->
<SolidColorBrush x:Key="PrimaryHueLightBrush" Color="#349FDA"/>
<SolidColorBrush x:Key="PrimaryHueLightForegroundBrush" Color="#FF333333"/>
<SolidColorBrush x:Key="PrimaryHueMidBrush" Color="#0288d1"/>
<SolidColorBrush x:Key="PrimaryHueMidForegroundBrush" Color="#FFDDDDDD"/>
<SolidColorBrush x:Key="PrimaryHueDarkBrush" Color="#015f92"/>
<SolidColorBrush x:Key="PrimaryHueDarkForegroundBrush" Color="#FFFFFF"/>
<!--ACCENT-->
<SolidColorBrush x:Key="SecondaryAccentBrush" Color="#FF50F350"/>
<SolidColorBrush x:Key="SecondaryAccentForegroundBrush" Color="#FFFFFF"/>
</ResourceDictionary>
</Application.Resources>
</Application>3.4 主窗体 MainWindow.xaml
添加菜单、设置菜单项切换动画等：
<Window x:Class="CustomMenu.MainWindow"
