</wnd:AppWindow>

• 如果设置了TitleBarContent, 需设置TitleBarHitTestType为TitleBarHitTestType.Complex, 否则会出现无法点击标题栏内容的情况
• 通过EnableWindowEffect(true) 启用窗口效果

* 设置启动页面, 继承IApplicationSplashScreen实现成员方法

• AppName 应用名称
• AppIcon 应用图标
• SplashScreenContent 启动页面内容
• RunTasks 启动页面任务
• MinimumShowTime 启动页面最小显示时间

using AvaloniaFluentUI.Controls.Windowing;

namespace Test.Views;

public partial class MainWindow : AppWindow 
{
    public MainWindow()
    {
        InitializeComponent();

        TitleBar.TitleBarHitTestType = TitleBarHitTestType.Complex;
        EnableWindowEffect(true);

        SplashScreen = new MainWindowSplashScreen();
    }
}

class MainWindowSplashScreen : IApplicationSplashScreen
{
    public string AppName => "Test";
    public IImage AppIcon => null;
    public object SplashScreenContent => null; 
    public Task RunTasks(CancellationToken cancellationToken)
    {
        return Task.Delay(1000);
    }

    public int MinimumShowTime => 1000;
}
