我从模板创建了一个默认的 MAUI 应用程序，我正在尝试调试它而不对其进行任何修改。该应用程序在调试模式下甚至不会启动，即使它在发布模式下启动得很好。还有其他人面临这个问题吗？任何解决方案/解决方法表示赞赏。

偶然发现面临类似问题的人：

https://youtrack.jetbrains.com/issue/RIDER-79838/Cannot-debug-macccatalyst-target-in-MAUI-project

让应用程序启动+调试的解决方案本质上就是这个（如果 5 秒不够长，您可能需要增加超时）：

public class Program
{
    // This is the main entry point of the application.
    static void Main(string[] args)
    {
#if DEBUG
        // silly workaround to allow debugging of macCatalyst apps
        //
        // https://youtrack.jetbrains.com/issue/RIDER-79838/Cannot-debug-maccatalyst-target-in-MAUI-project#focus=Comments-27-7970946.0-0
        Thread.Sleep(5_000);
#endif

        // if you want to use a different Application Delegate class from "AppDelegate"
        // you can specify it here.
        UIApplication.Main(args, null, typeof(AppDelegate));
    }
}

希望这可以帮助一些人节省一些时间。
