[PROBLEM SOLVED]
Well I found a solution thanks to Yossi2010 on StackOverflow: c# - TMPro not found in Visual Studio Code - Stack Overflow
Apparently, I was supposed to untick everything on the generate csproj files tab and THEN regenerate the project files:
Not sure why I had to do this, but I’m gonna say that by checking on one type of package, it prevents it from being regenerated. At least I got this problem solved.
Whenever I include a new directory from the UnityEngine namespace, Visual Studio Code doesn’t seem to recognize them, which will count these as errors despite the fact that Unity can read and process these scripts just fine. I’ve tried downgrading my unity vsc package and regenerating project files but neither of them worked. Is there any other method I can use that can fix this?
This may help you with intellisense and possibly other Visual Studio integration problems:
Sometimes the fix is as simple as doing Assets → Open C# Project from Unity. Other times it requires more.
Other times it requires you also nuke the userprefs and .vsconfig and other crufty low-value high-hassle files that Visual Studio tends to slowly damage over time, then try the above trick.
Barring all that, move on to other ideas:
Also, try update the VSCode package inside of Unity: Window → Package Manager → Search for Visual Studio Code Editor → Press the Update button
None of these work. Also Im trying to work with that last link but I don’t know where to input that command since that looks like something for Linux. I’m on Windows. I tried to reinstall the unity vsc component but it didnt work either so I really don’t know what else to do.
