如何在Maui中使用Autofac

public static MauiApp CreateMauiApp()
{
    var builder = MauiApp.CreateBuilder();
    builder
        .UseMauiApp<App>()
        .ConfigureFonts(fonts =>
        {
            fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
            fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
        });
#if DEBUG
    builder.Logging.AddDebug();
#endif

    // 添加以下代码
    builder.ConfigureContainer(new AutofacServiceProviderFactory((containerBuilder) =>
    {
        // Once you've registered everything in the ServiceCollection, call
        // Populate to bring those registrations into Autofac. This is
        // just like a foreach over the list of things in the collection
        // to add them to Autofac.
        containerBuilder.Populate(builder.Services);

        // Make your Autofac registrations. Order is important!
        // If you make them BEFORE you call Populate, then the
        // registrations in the ServiceCollection will override Autofac
        // registrations; if you make them AFTER Populate, the Autofac
        // registrations will override. You can make registrations
        // before or after Populate, however you choose.
        containerBuilder.RegisterType<MainPage>();
        containerBuilder.RegisterType<MainViewModel>();
    }));

    return builder.Build();
}

public partial class App : Application
{
    public App(MainPage mainPage)
    {
        InitializeComponent();

        MainPage = mainPage;
    }
}
