I have a Xamarin Forms app that I am updating to use Maui 9. In my app, there are a couple of places where I need to change the top-level page. I was able to do this by setting the MainPage property of the app.

The release notes for Maui 9 say to override CreateWindow to set MainPage at the start of the app, and use Application.Current.Windows[0].Page to get the page, but I can see no other way of setting MainPage… can anyone suggest how I can do similar to setting MainPage?
