MAUI Navigation

[ClaytonIndustries]

Hi I'm having trouble working out how to use the INavigationService in MAUI. In Xamarin Forms we used to override PrepareViewFirst to inject the NavigationPageAdapter object into the container. In MAUI though PrepareViewFirst is never called when using DisplayRootViewForAsync.

Here's what I've got

public App()
{
    InitializeComponent();

    Initialize();

    _container = container;

    _container.PerRequest<HomeViewModel>();
    _container.PerRequest<AnotherViewModel>();

    DisplayRootViewForAsync<HomeViewModel>();
}

// This is never called so no NavigationService will not get added to the container
protected override void PrepareViewFirst(NavigationPage navigationPage)
{
    _container.Instance<INavigationService>(new NavigationPageAdapter(navigationPage));
}

From looking at the source code I tried calling PrepareViewFirst() before DisplayRootViewForAsync and that successfully added a NavigationPageAdapter to the container however when INavigationService is injected into a viewmodel calling NavigateToViewModelAsync does nothing.

So how do we navigate between viewmodels in MAUI?

I'm using the latest beta version from MyGet

Have you tried calling DisplayRootView instead of DisplayRootViewForAsync?
