I've been working a little on the side lately to put together an article on NGEN for MSDN magazine. We finished with the final changes a few days ago, and just three days later I was suprised to see it already published on the website! MSDN Mag is running my article as a preview for the April issue. Take a look here: http://msdn.microsoft.com/msdnmag/issues/05/04/NGen/default.aspx. I'd be interested in getting feedback (if anyone is reading this) as to what other topics around NGen would be interesting.
