Not the person you asked, but I'm in a similar boat (15 years, polyglot but a lot of C#).

I mostly use VS Code to be honest. I use VSCode for other languages and for a long time it was the only graphical editor to have good remote development (over SSH) support.

Rider has that feature now though and is pretty nice too. I typically jump over to it when I need to profile something as it integrates with dotTrace. If you're coming from full-fat Visual Studio you'll probably prefer Rider.

Rider; however that's on a Windows work machine. We are a solid way to getting a linux/mac dev env going; maybe 30% is netstandard2.0, 10% is net9, the remainder net472 (including an old school non-sdk web app on IIS). Maybe ~ million LOC in its 14 year lifespan.

My personal dev is shifting to Rust.
