Yes, you can use vscode and rider. Rider isn’t free for companies and vscode has some free stuff, but Microsoft came out with a new extension for c# that requires a visual studio subscription. To me, this signals they will be directing the majority of their investment into this, rather than a free extension.

The experience isn’t as good in vscode (I haven’t used rider, but it costs money anyway, so still expensive) as it is in full fat visual studio.

At work, I use windows and full visual studio. At home, I use Linux and vscode.
