@bcooley: wow, that is a really nasty post. What you fail to realize is that Roslyn will make AOT very easy since c# code can be *dynamically converted into C++* and then *compiled as native*. Try to use your imagination for positivity instead of being negative and rude! This takes C# light years ahead.
Furthermore c# 4.0 was just recently released, even though they call this c# 5 (marketing) I think this is more of like the 2.0/3.0/3.5 pattern we saw in the past (hence no *actually* new runtime version).
