how to reset page in .NET 9.0

Question

Previously, we were resetting like this:

void Reset()
{
    (Application.Current as App).MainPage.Dispatcher.Dispatch(() =>
    {
        (Application.Current as App).MainPage = new AppShell();
    });
}

How can we do the same thing in .NET 9.0, since in 9.0 we are using Windows and no longer have AppShell redirection?

protected override Window CreateWindow(IActivationState? activationState)
{
    return new Window(new AppShell());
}

Answer 1

Hello,

You can replace Page by setting a static instance for Window.

Please refer to the following code:

public partial class App : Application
{
    public static Window WindowInstance { get; private set; }
    public App()
    {
        InitializeComponent();
 
 
    }
    public static void Reset()
    {
        WindowInstance.Page = new MainPage();
    }
    protected override Window CreateWindow(IActivationState? activationState)
    {
        WindowInstance = new Window(new AppShell());
        return WindowInstance;
    }
}

Best Regards,

Alec Liu.
