Visual Studio Code has nothing to do with Visual Studio proper other than the name, the logo and the fact that both are Microsoft projects. It's a pretty good text editor, actually - it's my Go IDE, thanks to the vscode-go plugin.
I just wish they hadn't named it like that, as it's a pain to open it (and Visual Studio) on Microsoft's own OS: if I want to open either of them, I'll begin to type "visual" after pressing Start, press enter... and with a bit of luck, it will be the "Visual Studio" I wanted to open. Worse is when I'm on it, and the guess doesn't change until I begin to type "Code" after typing the first two words. Really frustrating. So Microsoft's problem with names goes beyond codenames...
