Resolved . (dot) To see functions but they don't appear

I've been watching a youtube tutorial

(this is the tutorial if anyone is interested) and when the guy doing the tutorial presses . (dot) in the end of writing (for example gameManager.) under the dot appears the available functions for that.https://drive.google.com/open?id=1eKuaDa8yikZSDEliDnroVUMemrr1aDY9 (this is what I mean). I'm using visual studio 2019.

Is it available to make it appear for me too? If so how ? Did I do something wrong when installing unity/visual studio?

 

Try carefully following the steps in this thread: https://forum.unity.com/threads/intellisense-not-working-with-visual-studio-fix.836599/

 

Thank you so very much
