UWP _isInBackgroundMode

I am having a problem with my code.

Says the value is set, but not used...

I get the nice green line under bool _isInBackgroundMode = false;

What am I not getting here?

namespace MyApp
{
using Views;
using Windows.UI;
using Windows.UI.ViewManagement;

sealed partial class App : Application
{
    bool _isInBackgroundMode = false;

    public App()
    {
        this.InitializeComponent();
        this.Suspending += OnSuspending;

        this.EnteredBackground += App_EnteredBackground;
        this.LeavingBackground += App_LeavingBackground;

    }

    private void App_EnteredBackground(object sender, EnteredBackgroundEventArgs e)
    {
        _isInBackgroundMode = true;
    }

    private void App_LeavingBackground(object sender, LeavingBackgroundEventArgs e)
    {
        _isInBackgroundMode = false;
    }

This is because you don't have any code reading that value. As of now; or at least what you've shown; you are only setting the value and no where is it actually used (read from).

Once you write code that says something like

if (_isInBackgroundMode)
    doSomething();

Then the green line will go away.
