Microsoft HoloLens: Course 101E - Ch. 3

edited April 2016 in Questions And Answers

can anyone explain this to me:

// Set up a GestureRecognizer to detect Select gestures.

recognizer.TappedEvent += (source, tapCount, ray) =>
// Send an OnSelect message to the focused object and its ancestors.
if (FocusedObject != null)

what does this mean:

recognizer.TappedEvent += (source, tapCount, ray) => { }, what is inside (), why there is a "=>" sign?
