Seconded on both StackOverflow.com and asp.net.

Also, it's not really C#, but it might be helpful in terms of ASP.NET and OOP -- one of my personal favorites is 4 Guys From Rolla.

There are a few others I check out on occasion; I'll try to remember to post them here.

But as was said earlier, I'm not aware of anything like SSC. If there is, I wouldn't mind knowing about it myself.
