Here's a great post from nettuts outlining some key differences and new features.
I don't really have much to add on this, but just a few thoughts:
- A lot of changes seem to deal with allowing functions to be passed into methods. Being a .Net 3.5 guy, I'm love this anonymous delegate stuff, so it's good to see!
Yeah, that's all the comments I have right now. Told you I didn't have much to add!
