Yesterday I gave two workshops, Advanced NHibernate and Building DSL with Boo. I finished the day absolutely crushed, but I think they went very well.
Both were recorded, although I am not sure when they will be online.
Ryan Kelley has a blow by blow description of the NHibernate talk, and you can get the code for that here:
I'll post the code for the DSL talk shortly afterward.
I got some really positive feedback about the NHibernate Profiler, and I am very interested in demoing that and getting additional feedback when the real conference starts.
