Some time ago, Soma announced that WinFX was renamed to .NET 3.0. I was confused and didn't really get the idea behind this name change. But I was too busy with my diploma thesis and final exams that I didn't make the effort to further dig into this. 

Luckily, Jason Zander in this rockin' channel9 video explains it with a great detail. In just 30 minutes, I was able to get a broader view what's really behind .NET FX and how those pieces relate to each other. 

Strongly recommended. And don't forget to visit Jason's blog…
