WinUI 3 XAML创建AnimatedIcon报错：Source属性不支持AnimatedFindVisualSource类型

按照文档尝试添加动画按钮时，Visual Studio提示导入模块xmlns:animatedvisuals="using:ABI.Microsoft.Microsoft.UI.Xaml.Controls.AnimatedVisuals"，但导入后出现错误：

XLS0504 The "Source" property does not support values of type "AnimatedFindVisualSource".

我的代码： #

<?xml version="1.0" encoding="utf-8"?>
<Window
    x:Class="MyApp.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:MyApp"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:animatedvisuals="using:ABI.Microsoft.Microsoft.UI.Xaml.Controls.AnimatedVisuals"
    mc:Ignorable="d"
    Activated="Window_Activated">

    <Grid>
        <StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center">
            <Button x:Name="myButton" Click="myButton_Click">Click Me</Button>

            <Button PointerEntered="Button_PointerEntered" PointerExited="Button_PointerExited" Width="75">
                <AnimatedIcon x:Name="SearchAnimatedIcon">
                    <AnimatedIcon.Source>
                        <animatedvisuals:AnimatedFindVisualSource/>
                    </AnimatedIcon.Source>
                    <AnimatedIcon.FallbackIconSource>
                        <SymbolIconSource Symbol="Find"/>
                    </AnimatedIcon.FallbackIconSource>
                </AnimatedIcon>
            </Button>
        </StackPanel>
    </Grid>
</Window>

错误原因： #

• 引用了错误的命名空间：ABI.Microsoft.Microsoft.UI.Xaml.Controls.AnimatedVisuals是系统内部的ABI（应用二进制接口）命名空间，仅用于底层交互，不允许开发者直接使用。正确的命名空间应为xmlns:animatedvisuals="using:Microsoft.UI.Xaml.Controls.AnimatedVisuals"，去掉前缀ABI.即可。
• 依赖库配置问题：AnimatedFindVisualSource属于WinUI 3控件库，需确保项目已正确安装并引用Microsoft.UI.Xaml（WinUI 3）包，且项目类型为WinUI 3兼容的应用（如Desktop WinUI 3应用、集成WinUI 3的UWP项目）。
