Useless unless what you REALLY want is "Visual Web Developer for Dummies". From the introduction: Microsoft has implemented powerful design-time tools in Visual Web Developer, so why not use them to be more productive? Whenever possible, I favor the drag, drop, choose, and configure methods over typing code.
So if you want to understand how ASP works, write the code yourself, or use any other editor... you're out of luck. I'm just glad I borrowed this from the library rather than wasting money on it.
