As others mentioned, you can't get IntelliSense for local vars. However: If your function is so large that a "regular" comment is not close enough to read near the place where you're using the var, then the right fix is to refactor the function -- break it up into multiple, smaller methods, with fewer vars. I don't think this feature should exist, as it would serve only to facilitate writing excessively large functions.
