Visual Studio doesn't run on UNIX, nor mainframes.
Even Visual Studio Code is more performant than Eclipse and you can create a Linux distributable of .Net and deploy to Linux from Visual Studio. And before you say there are non Linux mainframes. Yeah I know - another dead end technology along with .Net framework and C++/CLI.
And that not forgetting that VSCode doesn't do even 10% of what Eclipse or VS do.
