Unity debugger plugin and C# plugin are installed but Visual Studio Code does not recognize Unity APIs. Intelisense does not work. How can I fix?
I had the same problem happen to me several times in my last project. You should first check the usual solution : Go to Preferences -> External tools and set vs studio as external script editor (of course make sure that in visual studio you have Tools for unity installed.) Now if that is already set, witch probably is, you can click Regenerate project files that fixed it for me.
