@kennyzx thank you for pointing the link to me. here is hoe I solved my problem by placing the code below in my 'App.xaml.cs'

protected async override void OnWindowCreated(WindowCreatedEventArgs e)
    {            
        //Lunch ContentDialog
        LoginPage signInDialog = new LoginPage();
        await signInDialog.ShowAsync();

        if (signInDialog.Result == SignInResult.SignInOK)
        {
            // Sign in was successful.

        }
        else if (signInDialog.Result == SignInResult.SignInFail)
        {
            // Sign in failed.
            // Exit the app after three attempts                
            Application.Current.Exit();
        }
        else if (signInDialog.Result == SignInResult.SignInCancel)
        {
            // Sign in was cancelled by the user.
            // Exit the app
            Application.Current.Exit();
        }
    }
