// Event Handlers - Activations
protected override void OnLaunched(LaunchActivatedEventArgs e)
// Occurrence
// - when user launches app (ie. tile selection)
// - during prelaunch, when system launches app
// Assumptions
// - prelaunch is disabled by default (post v1607)
// - when enabled, may be prelaunch or may have already prelaunched
// - app may not immediately be visible (eg. prelaunch)
// - previous state unknown (eg. user terminated, system terminated, crashed/hasn't-run, suspended, running)
// - app will feel unresponsive if execution exceeds a few seconds
// Actions
// - initial app resources and state
// - register event handlers
// - configure and set initial page (on user launch)
// - display splash screen (on user launch)
// - (utilize custom SplashScreen if initialization requires more time)
