I changed my IDE to VS Community 2019 and followed the steps beforehand, but it’s not operating the way it is in the video. Should I just do it manually? If so, how?
I’m not sure what you mean by “inline variable”…
Are you referring to the Intellisense? For this, you need to make sure that you’ve selected Visual Studio 2019 as the External code editor in Editor/Preferences/External Tools.
Make sure the Visual Studio Community package in is up to date in Window/Package Manager.
Regenerate Project files in the Editor/Preferences/External Tools as well.
