Visual Studio has spoiled us .NET developers. In Visual Studio we have a GUI that does everything for us: compiling, source-control, editing, you don’t even have to remember class or method names because of auto-complete and parameter guessing! It is all there and it holds your hand and it feels safe and easy.
The next version of ASP.NET is going to use a lot of the web functionality that many .NET devs have never seen: NPM, Bower, Grunt, and others. Visual Studio will probably cover the front-end of those things, but it will be invaluable for you to learn them the way they were meant to be used: from the command-line.
