Hi, I’m sorry if this is a dumb question, but when getting started with the C# vers I have the error ‘the type or namespace name could not be found’ for tobii_gaze_point_t, and ‘using directive is unnecessary’ for Using Tobii.StreamEngine. I’ve pasted the files into the tobii directory and commented/changed the code as per the instructions here: https://developer.tobii.com/product-integration/stream-engine/getting-started/ I’m not sure what I’ve done wrong.
