How do I download the videos?
- To download, right click the file type you would like and pick “Save target as…” or “Save link as…”
Why should I download videos from Channel9?
- It's an easy way to save the videos you like locally.
- You can save the videos in order to watch them offline.
- If all you want is to hear the audio, you can download the MP3!
Which version should I choose?
- If you want to view the video on your PC, Xbox or Media Center, download the High Quality WMV file (this is the highest quality version we have available).
- If you'd like a lower bitrate version, to reduce the download time or cost, then choose the Medium Quality WMV file.
- If you have a Zune, WP7, iPhone, iPad, or iPod device, choose the low or medium MP4 file.
- If you just want to hear the audio of the video, choose the MP3 file.
Right click “Save as…”
- Mid Quality WMV (Lo-band, Mobile)
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
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.
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.
