NonCompiledXaml.axaml代码

<Window xmlns="https://github.com/avaloniaui"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        mc:Ignorable="d" d:DesignWidth="800" d:DesignHeight="450"
        x:Class="AvaloniaUI.NonCompiledXaml"
        Title="NonCompiledXaml">
    <ScrollViewer>
        <StackPanel Name="mainPanel" Background="#f0f0f0">
            <TextBlock Text="&#xe6e5;" FontFamily="{StaticResource IconFont}" FontSize="20" Margin="5" HorizontalAlignment="Center"/>
            <Button Content="加载动态内容" Click="Button_Click" Margin="0,0,0,5"/>
        </StackPanel>
    </ScrollViewer>
</Window>

NonCompiledXaml.axaml.cs代码，其中Window1是一个简单的Window窗口。新扩展已经支持多个cs文件编译，并且支持AvaloniaUseCompiledBindingsByDefault = true
