The second day already and packed with sessions again. It seems that there's not that much really new coming up, but it's been very usefull catching up again. What were the highlights up until now?
The parallel additions in .NET 4.0. Whether you like it or not you'll need them to leverage the power in todays multi core machines. It will probably bring a challenge to analysis and design to include this parallel thinking here as well.
And it's not new as the launch is expected in November, but if you're lagging behind at the moment like I am, you certainly have to make time for it now; the Azure platform. I did make a mental note to have a closer look at the security aspects and the impact on the development lifecycle, so I might get back on that later.
Still one more day to go...
