Today was a 6 hour to San Francisco to speak at Bay.NET, Oliver Nguyen's INETA group. This is a very well run group, all kinds of meetings, sub-groups, and cooperation with the entire development community in the Bay Area. I spoke on n-Tier development and .NET, using all kinds of great technologies like application blocks, WS-Security and custom business objects. To see the presenation live, you can check out the MSDN Webcast I did on “Constructing an n-Tier Windows Forms Application Using Microsoft Application Blocks“ or just download the Tracker application and the eBook on DevCenter.
