I recently helped out on a ASP.Net project after doing projects in other Web Application stacks for a couple of years. And let me tell you it was painful. I haven't done any research into what Microsoft is promising in the next version to come out with Visual Studio 2008 but getting back into this stuff made my brain hurt.

I would tend to categorize ASP.Net development as abuse of your technical resources. The process is indeed painful for one reason or another. And it's a bit baffling to me why there is so much demand for it.
