This isn’t really DOTS-specific, but how can a person open, for example, GenerateAuthoringComponentAttribute.cs in visual studio, and use “find all references” to see what [GenerateAuthoringComponent] does mechanically? Its like VS is opening it as a text file rather than a holistic project and seeing references between classes.
For what its worth, adding in a breakpoint and connecting VS to Unity and causing the breakpoint to be hit (ie running some code), seems to get things visible and navigable
