Both available from the extension marketplace.
I hate this a lot. It's gotten so bad the last couple of releases to the point that I try and use VS Code more in lieue of VS except debugging.
How they could let such fundamental functionality get broken is beyond me.
The only reasons I use VSCode are the plugins I cannot get on VS, like Powershell, Rust, Azure tooling, and for stuff like Next.js, better use an editor that is anyway a browser in disguise.
Performance has never been a part of my decision flowchart.
I keep both editors open, but VS is basically just there to hit the compile button and for the occasional debugging.
Better not having Resharper around.
