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
