I've been using MS Visual Web Developer 2008 Express Edition to develop my (very simple) aspx web pages. Is there any reason I cannot use Visual Studio 2012 Express instead?
Maybe it's the programer Visual studio is fine, the express is the free version and can do most everything the paid version can just with a bit of bloat. I'd try to get a legit copy of vs2010, 2012 is out but I wouldn't suggest using it yet.
Okay, but one thing about Visual Web Developer is it has a mini-IIS built into it. So you can emulate your web pages, i.e. it fires up a little web service of some sort and serves up your page if you request it. And it does this without having to run IIS. Does Visual Studio have anything like that?
"Visual Web Developer" is part of visual studio express, and yes to debug/test your pages it will setup a temporary local host
