Does VisualStateManager.GoToState return when the animation completes?

Question

As the title mentions, does VisualStateManager.GoToState return once the state transition completes if I specify UseAnimation = true? Or does it return instantly and the animation runs later?

Answer 1

The animations can take any amount of time, depending on the transitions that were authored.

As all transitions are implemented via storyboards and storyboards are running animations asynchronously, your code will return immediately and the animations will play on in the background (even zero-time ones do this).

Answer 2

There is an extension of VSM here that allows for executing a delegate after the transistion completes.
