如何在Avalonia中创建一个单独的样式文件？

<ResourceDictionary xmlns="https://github.com/avaloniaui"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

    <Style Selector="Button">
        <Setter Property="Background" Value="Blue"/>
        <Setter Property="Foreground" Value="White"/>
        <Setter Property="FontSize" Value="14"/>
    </Style>

    <Style Selector="TextBlock">
        <Setter Property="Foreground" Value="Red"/>
        <Setter Property="FontSize" Value="16"/>
    </Style>

</ResourceDictionary>

<Application xmlns="https://github.com/avaloniaui"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:YourNamespace">

    <Application.Styles>
        <StyleInclude Source="styles.xaml"/>
    </Application.Styles>

    <!-- 其他应用程序内容 -->

</Application>

<Button Content="Click me" Style="{StaticResource Button}"/>
