just changed to Visual Studio 2013 Express from 2010,
I am trying to learn by reviewing some snippits. I used to be able to hover over the code, and info relating to the object, data type, class, etc... would pop-up.
I'm pretty sure intellisense doesn't work if you're just copy + pasting code. You have to put it in a project (or at least try to run it). At least I think so.
