Frank has got the scoop on the availability of SSCLI 2.0 (hint, its ready now!). I’m a fan of the SSCLI, its a great learning tool especially when you want to see how the folks at Microsoft tackle certain challenges. The best thing about it is if you want to try out one of those “what-if-the-runtime-did-this” scenarios you can just go and hack the code – provided you stay within the terms of the license agreement of course.
