If you are like me and did the two previous lessons - keyvault and storage... and now want to open a new folder ... VSCode might complain! You might need to set up a multiroot workspace to follow this tutorial. Is quite simple to set-up a workspace and add folders to it. The official docs as of now are not great about it though. Also it adds one more abstraction which might be distracting. The main benefit is that is much cleaner longer term. Else you end up with tons of folders with similar names and concepts on your disk drive.
