Hi @ciscal, @morokot, unfortunately the Gaze SDK is now deprecated and is no longer being provided publicly.
However, we have since created a replacement low level API available @:
https://www.nuget.org/packages/Tobii.StreamEngine.Native/
https://www.nuget.org/packages/Tobii.StreamEngine/
This is a low level API so please only use it if you know why you are doing it. Very little support is going to be provided.
Please try it out and let us know if this fits your needs.
