The quickest way I have to seen to learn ASP.Net is this 6-hour MSDN video series. Six hours of .Net in 30-minute slices. You will like these tutorials, if...
...you find books slow and boring
...you want to "get" your .Net developers' geek talk
...you like seeing how things are done, to reading a lot of theory
...you've always wanted to know more about .Net
And if you like this, you might want to head over to LearnVisualStudio.Net, the folks who created the tutorial and check out their advanced lessons. I took the $100 "Lifetime Membership", and yes I think it's a steal.
