I have just begun trying to learn C# with Unity. I'm following guides and tutorials. In these guides I see auto completions that my visual studio code is not showing me.
For example, in one video I see the following auto-completion:
On my own installation, I see the following:
Note that the auto-completion is not hinting Destroy. Other methods/functions such as GetComponent are also not auto-completed.
I believe that the correct folder is opened in VSC.
Visual studio code is set as my default editor in unity as per this question.
I have installed the .Net Core Extension Pack, which includes the C# extension pack for VSC. What am I missing?
