I am developing a program for the WIN UI. You must call ContentDialog and enter the user’s password.

public async Task<bool> enterPasswordAsync(modeCheckPassword checkPassword)
{
    var content= new PasswordBox{Height = 32};
    ContentDialog dialog = new ContentDialog();
    dialog.XamlRoot = frame.XamlRoot;
    dialog.Content = content;
    dialog.Style = Application.Current.Resources["DefaultContentDialogStyle"] as Style;
    dialog.Title = "Введите пароль";
    dialog.PrimaryButtonText = "Войти";
    dialog.SecondaryButtonText = "Отмена";
    dialog.DefaultButton = ContentDialogButton.Close;

    ContentDialogResult result = await dialog.ShowAsync();

    while (true)
    {
        if (await dialog.ShowAsync() == ContentDialogResult.Primary)
        {
            if (checkPassword.Invoke(content.Password))
                return true;
        }
        else
            return false;
    }
}

In debugging mode, I looked at what point the program was hanging. Freezes when calling ShowAsync.

When calling ContentDialog, my program freezes and does not process anything anymore. However, calling a simple ContentDialog does not cause any problems.

I watched the project on this site. https://xamlbrewer.wordpress.com/2022/03/09/a-dialog-service-for-winui-3/

I looked at the official Microsoft website https://learn.microsoft.com/ru-ru/uwp/api/windows.ui.xaml.controls.contentdialog?view=winrt-26100#derived_controls_with_winui_styles
