Hi @snowymo, if you are new to the concepts of eye tracking programming, then indeed it might be worth you looking at the Core SDK samples as we demonstrate in several different contexts how to create gaze aware components, specifically for the WPF framework.. which may be what you are looking for?
Although there are no extra ‘features’ per se in the Core SDK, our samples are more explicit and should ideally help you get up and running quickly and to understand how to easily create gaze aware component within your program.
have a look at the ‘WPF’ samples which should hopefully make things clear and let us know if we assist further. Best Wishes.
