One thing that got pretty heavy mention at the MVP summit was Visual Studio Code. Turns out this is awesome. I reckon that if aliens ever come to earth it won't be to steal our water or turn us all into their slaves or whatever. It will be to get hold of Visual Studio. It is the best place in the universe to write code.
Visual Studio Code is a lightweight development environment that takes the essence of the Visual Studio development process and makes it work on Lunix, Mac OSX and Windows. It is designed to be extensible, so that you can create bindings for your own development process and programming language (although there are lots available already). And it's free. Great stuff.
Perhaps by beaming the installer out into space we can save ourselves an alien invasion or two.
