Is application active ?

Question

How can i detect if application is currently active (on top) or running in background ?

Answer 1

What do you mean by the app being active? What scenario are you trying to enable?

You can watch CoreWindow.Activated to see when your host window is activated and deactivated.

Apps will suspend when they aren't being used and won't run any code. For key background scenarios they can move the processing to a background task.

CoreWindow.Visible property

to observe changes listen to VisibilityChanged

Xaml maps Visible into Window.Visible
