Thottam has a good overview of the 3 day event, as does DevHawk and OakLeaf. F# in action. SecondLife (Mono) was one of the topics discussed, but I still can’t find the slides on the web :( – I believe RAIL is used as part of the implementation. Christopher’s CAT slides can be found here. Classbox is explained a little here together with a question on C# 4.0. Gray Flake slides are available here on Internet Singularity.
