Windows store app suspend/terminate handling

By default it doesn’t seem like Unity is doing anything with suspend/terminate in a Windows store app. Also, it seems like if I alt+tab away from my app it should pause like the player does in editor, but it doesn’t. Are these things I need to do myself in app.xaml.cs, or am I missing something?

I needed to implement “void OnApplicationPause(bool pauseStatus)” on my game controller, then set Time.timeScale = 0, and whatever my game needed when pausing.
