Visual Studio express comes in different editions, so it's unlikely that Visual C# Express installed Visual BASIC, as that was what Visual BASIC Express is. And running the Express for Web 2013 installer says it will use less than 1GB of disk space.

What that out of the way, within five seconds of clicking the link here it computed 7GB of disk space. It did not provide options to ignore subcomponents like the full VS 2013/4.

My experience is that the MS tools stuff installs and uninstalls cleanly -- and what little it leaves behind are some system components that I'd prefer to have updated and left around anyway. If this freaks you out then that's what VMs are for.
