I just completed the incredibly painless process of porting my web site from ASP.NET v1.1 and Wilson.MasterPages to ASP.NET v1.2 and it's integrated MasterPages.
All I can say is WOW.
I trimmed my 7 page site down from 57 files in 2 directories to an astounding 9 files (none of these figures are counting images of course). While most of the deprecated files were CodeBehind pages and .resx files, I'm still impressed. No more fooling around with UserControls at all when trying to seperate code from UI!!
While I'm on the topic I must also say that I really like inline code. I guess it's because of all of my classic ASP experience, but I find it easier to have everything right there in front of me.
Anyway, major kudos to the whole ASP.NET team!
Grr. Robert pointed out to me that there is no GoLive license for v1.2 yet, so until I get any clarification on this I went ahead and switched back to the 1.1 version of my site. I am interested to hear any clarification of this though, so I would appreciate any comments from anyone with more knowledge of this. I certianly don't want to upset anyone...
