Editor: Windows
Why not Linux, MacOS, too?
Someone would have to make it, no one has made it yet.
Not at this time, but since Visual Studio runs on both Mac and Linux, it could happen in the future.
Just to be clear, Visual Studio does not officially run on anything other than Windows.
However, as the linked blog post indicates, since this is .NET based you can use any IDE or code editor you like that has support, such as Visual Studio Code, or JetBrains Rider, which are available for Linux and macOS.
The game engine's own editor is also Windows only and presumably if that is .NET based then one day it might be cross platform if the community makes it happen. That doesn't really relate to Visual Studio though.
Visual Studio for Mac was shut down (it wasn't even really Visual Studio, btw), and I don't believe it's ever worked for Linux.

I think I saw a comment on github about that. It's definitely something that someone is working on.
