Screencast: Building N-Tier Applications in Visual Studio 2008

Channel 9 has made available their latest screen cast: Building N-Tier Applications in Visual Studio 2008

From the site:
In this in interview John Stallo, a Program Manager on the Visual Basic Team, talks about WCF and simple N-Tier applications. He talks about a specific architecture scenario and some of the pain points we have building n-tier applications today. He then walks us through the improvements made in the DataSet Designer that physically separates the data access from the structure and validation code and then quickly creates a WCF service and a client that demonstrates this architecture.
