After upgrading to Unity 2020.2.0a9 and then downgrading to 2019.3.12f1 things got messed up in visual studio (both in visual studio 2019 & 2017 community edition). My editor scripts (in Assembly-CSharp-Editor) are no longer able to reference objects in regular scripts residing in Assembly-CSHarp.
The code still compiles fine in the unity editor, but not in visual studio. I no longer have access to intellisense and the visual studio is flooded with errors that makes it hard to work with.
What is going on?
