为什么默认WinUI样式中的条件XAML设置器在UWP中无效？

我将默认的WinUI按钮样式从WinUI GitHub repo复制到一个空项目中。下面是我的App.xaml。当我尝试运行该项目时，我得到这个错误：XAML二进制格式（XBF）生成器报告语法错误“0x03e9”。如果删除条件setter，它将运行。控件模板内的条件XAML工作正常。哪里出错了？

我猜您的问题与这个已知的issue有关，它基本上说您不能将Setters与Conditional XAML一起使用（目前？）。
您可以找到一个变通方法here。首先创建一个基本样式，然后使用Conditional XAML创建样式。

        <contract7Present:Style
            x:Key="DefaultButtonStyle"
            BasedOn="{StaticResource DefaultButtonBaseStyle}"
            TargetType="Button">
            <Setter Property="BackgroundSizing" Value="InnerBorderEdge" />
            <Setter Property="Padding" Value="{StaticResource ButtonPadding}" />
            <!--<Setter Property="CornerRadius" Value="{ThemeResource ControlCornerRadius}" />-->
        </contract7Present:Style>

        <contract7NotPresent:Style
            x:Key="DefaultButtonStyle"
            BasedOn="{StaticResource DefaultButtonBaseStyle}"
            TargetType="Button">
            <Setter Property="Padding" Value="11,5,11,5" />
        </contract7NotPresent:Style>

    </Application.Resources>

</Application>

顺便说一句，我注解掉了这一行，

<!--<Setter Property="CornerRadius" Value="{ThemeResource ControlCornerRadius}" />-->

因为在我示例应用程序中找不到ControlCotnerRadius。
