StudioTracking.Instance in Sdl.View.Sample??

I am trying to build one of the sample programs in the SDK documentation, SDL.View.Sample.  It references, repeatedly and seemingly critically, something called StudioTracking.Instance.GetViewWatch, which is not defined, nor is anything called "GetViewWatch" known to Visual Studio when all the SDL automation/plugin references are loaded.

Am I missing something?  How can I search for it?  Where is this documented, and what does it do?

Thanks,

Bernie
