As seen in the image bellow, references are not showing up in visual studio. I was just using visual studio and i closed the project opened some other project and opened the unity project again in visual studio. But then none of the references shows up and i cant really fix it.

Any ideas on how to fix this?

In Unity Editor try: Edit -> Preferences... -> External Tools -> Regenerate project files

This problem happened to me, I couldn't solve it, I reinstalled visual again and downloaded c# plugins and module so it worked
