Today I gave a training to 13 people about .NET 3.0. I recycled yesterday's session on WPF (there was only one person who already saw it yesterday - who got to do same extra labs) then went on with WCF and WF.
However, can you imagine training people in .NET 3.0 in a single day? I mean, it's very hard to give an overview of most of .NET 3.0's features in a single day...
