OK, OK, so C# 3.0 is only just out of the door. As anyone who has been reading my stuff for a while will have realized, I like what they've done with the language. Here at PH, we have now fully migrated all our solutions to Visual Studio 2008, and can now use C# 3.0 language and .Net 3.5 framework features everywhere they're useful. This makes me happy (though some annoying issues migrating to Web Deployment Projects 2008 decidedly aren't making me happy).

I haven't thought long and hard about what I'd really like in C# 4.0. I think I need C# 3.0 to settle in a bit more. I've used it quite a bit, but it takes a while to fully realize the power of all that is there, and I certainly don't want to start suggesting additions to the language when there is already a perfectly good solution to that problem...
