Which C++ Complier to choose?`

I’m trying to make the switch from Arduino IDE to VSCode. Every time I start VSCode, it tells me, “You do not have IntelliSense configured. Unless you set your own configurations, IntelliSense may not be functional. Select Compiler.” What is the correct course of action to take at this point?

Thank You

Such a popup shouldn’t even be popping up in the first place. It seems to me you have conflicting extension installed.

Are you sure you have a PlatformIO project opened? Please show a screenshot of VSCode with the File Explorer sidebar open and the content of your Extensions sidebar.
