Manually Showing MainWindow.xaml In App.xaml.cs (Dependency Injection)

Hey! My code is supposed to manually show MainWindow.xaml, but it doesn't if I remove StartupUri="MainWindow.xaml" and I get the error that is listed with details below with it. Without it, I get no error, so it must be my logic. The way I wrote it is because of dependency injection for AppLanguageServices. App.xaml

<Application x:Class="computerComponentsTracker.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

<Application x:Class="computerComponentsTracker.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

App.xaml.cs

private static IServiceProvider? ServiceProvider;

protected override void OnStartup(StartupEventArgs e)
{
    var serviceCollection = new ServiceCollection();

    // Register services
    serviceCollection.AddSingleton<IAppLanguageServices, AppLanguageServices>();
    serviceCollection.AddTransient<ComponentUsage>();
    serviceCollection.AddTransient<MainWindow>();
    serviceCollection.AddTransient<Settings>();

    // Build service provider
    ServiceProvider = serviceCollection.BuildServiceProvider();

    // Manually create and show MainWindow
    var mainWindow = ServiceProvider.GetRequiredService<MainWindow>();
    mainWindow?.Show();

    base.OnStartup(e);
}

private static IServiceProvider? ServiceProvider;

protected override void OnStartup(StartupEventArgs e)
{
    var serviceCollection = new ServiceCollection();

    // Register services
    serviceCollection.AddSingleton<IAppLanguageServices, AppLanguageServices>();
    serviceCollection.AddTransient<ComponentUsage>();
    serviceCollection.AddTransient<MainWindow>();
    serviceCollection.AddTransient<Settings>();

    // Build service provider
    ServiceProvider = serviceCollection.BuildServiceProvider();

    // Manually create and show MainWindow
    var mainWindow = ServiceProvider.GetRequiredService<MainWindow>();
    mainWindow?.Show();

    base.OnStartup(e);
}

How to Correctly Reference a Method in App.xaml.cs

Hey, reviewer. The ChangeLanguage method should work, but referencing is a challenge at the moment, since I get the error 'App' does not contain a definition for 'ChangeLanguage' and no accessible extension method 'ChangeLanguage' accepting a first argument of type 'App' could be found (are you missing a using directive or an assembly reference?). The OnLanguageChanged method works until I add that reference for ((App)Application.Current).... How do I correctly reference to a method in App.xaml.cs? ---- Settings.xaml.cs

    public partial class Settings : UserControl
    {
        public Settings()
        {
            InitializeComponent();
        }

        private void OnLanguageChanged(object sender, SelectionChangedEventArgs e)
        {
            string? selectedLanguage = ((ComboBoxItem?)e.AddedItems[0]).Tag.ToString();
            Debug.WriteLine(selectedLanguage);
            ((App)Application.Current).ChangeLanguage(selectedLanguage);
        }
    }
}

    public partial class Settings : UserControl
    {
        public Settings()
        {
            InitializeComponent();
        }

        private void OnLanguageChanged(object sender, SelectionChangedEventArgs e)
        {
            string? selectedLanguage = ((ComboBoxItem?)e.AddedItems[0]).Tag.ToString();
            Debug.WriteLine(selectedLanguage);
            ((App)Application.Current).ChangeLanguage(selectedLanguage);
        }
    }
}

App.xaml.cs

public partial class App : Application
{
    public void ChangeLanguage(string language)
    {

public partial class App : Application
{
    public void ChangeLanguage(string language)
    {

✅ Ways to Add Language Support (WPF)

I'm creating a hardware monitor software that will show statistics of (primarily internal) components. There is a monitor and a settings user control to switch between the two. There are two user controls for the controls themselves and then a window, which is MainWindow that serves as the median between these two. How would I go about switching languages dynamically in my XAML when a selected ComboBoxItem for a language is selected, which is applied upon clicking on the apply button? Like methods of implementation.
