C# Avalonia动态加载xaml和cs实例
扩展请参考https://www.cnblogs.com/dalgleish/p/18972924NonCompiledXaml.axaml代码
<Window xmlns="https://github.com/avaloniaui"

<ScrollViewer>
<StackPanel Name="mainPanel" Background="#f0f0f0">
<TextBlock Text="" 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
