Check out Doug's post and Don's post about Oslo. Finally, we're ready to talk about Oslo at the PDC. I've been involved in Oslo since late 2006, when we were still trying to define what it really is! I personally work on the .NET Framework 4.0 which is the underlying framework that drives Oslo. At the PDC, we will unveil Oslo and the improvements and changes we're making in the .NET Framework 4.0. Hopefully that will break the silence.
