Well there are a few code editors in the Store already, though you can't compare them to Visual Studio. For that you are going to need to upgrade Windows 10 S to Pro except if MS does some magic and ports Visual Studio to the Store.
Coding on a quick boot with visual studio would be amazing! Plus with 14 hours of battery life it would be great to code not in an office. So many possibilities.
what are the technical issues with Visual Studio being Centennial ported to the store? Is Win32 required for it to deliver the edit/compile/debug features of VS?

Windows has a plenty of good options for IDE, e.g. PyCharm is fantastic for developing in Python. And a versatile and powerful text editor, EditPlus, one of the major reasons why I use wine on my Linux machine.
If you only want to do HTML and CSS it can work but I don't think you want to code in those languages.
Other possibility, you only write code on the SL and you test it on a different PC.
