How to update culture on CoreApplicationView when I changing culture in main window?

Question

I have multiple views app, and I want update culture in runtime (using setting page). For main window I do this:

ApplicationLanguages.PrimaryLanguageOverride = currentCulture.Name;
Windows.ApplicationModel.Resources.Core.ResourceContext.ResetGlobalQualifierValues();
var currentFrame = Window.Current.Content as Frame;
currentFrame.Navigate(currentFrame.Content.GetType());
Globals.Navigation.OnCanNavigate(new NavigateEventArgs { TargetPageTag = NavigationItem.Home });

Its work correctly, but my CoreApplicatioViews dont change culture. I cant do the same for CoreApplicationView, because I dont have his frame for navigation.

Hello, Welcome to Micorosoft Q&A,

but my CoreApplicatioViews dont change culture. I cant do the same for CoreApplicationView, because I dont have his frame for navigation.

If you want to refresh the secondary ApplicationView from your main window. the better way is using Messenger send refresh command to secondary, and refresh secondary internal

For example

MainView

private void AlterButton_Click(object sender, RoutedEventArgs e)  
{     
    Messenger.Default.Send<bool,OtherPage>(true);  
     
}  

Secondary

protected override void OnNavigatedTo(NavigationEventArgs e)  
{  
    base.OnNavigatedTo(e);  
    Messenger.Default.Register<bool>(this, async (s) =>  
    {  
        await Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>  
        {  
            Reload();  
        });  
  
    });  
}  
  
public bool Reload() { return Reload(null); }  
private bool Reload(object param)  
{  
    Type type = this.Frame.CurrentSourcePageType;  
    if (this.Frame.BackStack.Any())  
    {  
        type = this.Frame.BackStack.Last().SourcePageType;  
        param = this.Frame.BackStack.Last().Parameter;  
    }  
    try { return this.Frame.Navigate(type, param); }  
    finally { this.Frame.BackStack.Remove(this.Frame.BackStack.Last()); }  
}  

For using Messenger you could refer mvvmlight Messenger document.
