Description
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.
Here's the step-by-step walkthrough of what John demonstrates.

The Discussion

NetRebel Very good video. This sample application in VB .Net 2008 could be very useful to many. Can you please post a link to this source?
Thanks
-
funkyonex I don't have the sample application used but I'm working on a set of How-Do-I videos that will be posted on the VB Dev Center when they are ready. Thanks!

Dudleigh C# Tutorial available here -
NetRebel Thanks for the planned post of these videos.
This sample application using an N-tier layout as illustrated in this video when combined with the (new) separation of of the TableAdapters and DataSet is just something that will be gold to have a sample of for learning reference.
