Building N-Tier Applications in Visual Studio 2008

Posted By: Beth Massi | Sep 10th, 2007 @ 11:39 AM | 27,023 Views | 7 Comments
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.

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 Smiley

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!

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.

Hi fguerrache,
 
I am behind on the How-Do-I videos but the walkthrough link I posted above details what is involved. I'll get back on the videos right after the holidays!

Thanks for your patience.
