Description
Describe the bug
If implementing INavigationAware in a Page, the methods are being called twice, redundantly,
To reproduce this issue, I have inherited INavigationAware in the AllControlsPage under the Wpf.Ui.Gallery folder. Then, I have output some information in the OnNavigatedTo method, and this information is being output twice
To Reproduce
public partial class AllControlsPage : INavigableView , INavigationAware
{
public AllControlsViewModel ViewModel { get; }
public AllControlsPage(AllControlsViewModel viewModel)
{
ViewModel = viewModel;
DataContext = this;
InitializeComponent();
}
public void OnNavigatedTo()
{
Debug.WriteLine("==== NavigatedTo");
}
public void OnNavigatedFrom()
{
}
}
we can show debug output :
==== NavigatedTo
==== NavigatedTo****
Expected behavior
There is an error with INavigationAware on the page class

Research direction
Start with the AllControlsPage implementation in the Wpf.Ui.Gallery folder and inspect how its INavigationAware methods are reached during navigation. Reproduce the issue using the shown Debug.WriteLine in OnNavigatedTo, trace both calls through the navigation entry points, and consider the issue done when navigation invokes the method once.
