@PureWeen do we have anything tracking this issue?

Hey @markusroessler why wouldn't you do ? Seems creating the empty navigation doesn't make to much sense.

new NavigationPage(new MainPage())

[markusroessler]

@rmarinho We use a MVVM framework that takes control of navigation after we initialized the empty NavigationPage. So the initial page is also set by the framework.

@rmarinho any news on this? We are currently migrating several XF apps to MAUI and this issue hinders us from completing the migration.
