Visual Studio is not seeing the MonoBehavior class.
I have tried un-installing and re-intalling several times and with both 2019 and 2020 versions.
When Visual Studio is opened, all of the correct using statements are at the top. MonoBehavior is not highlighted so auto-complete and class inspection/declarations don't work.
When I write code and then try to play it in Unity, it throws an error and won't play.
Has anyone else seen this behavior? Thank you!
