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 Erik Meijer, an Architect on the Data Programmability team, shows us how LINQ to XML works in the next version of Visual Basic, 9.0. He talks about some of the history behind the features as well as how XML literals, unique to
Visual Basic, are implemented. He takes us on an adventure on how to efficiently work with XML using XML Intellisense and an Office Open XML Excel document, pointing out a lot of tid-bits of information along the way that only Erik could show us.

Both awesome and timely - there I was struggling with namespaces in xml for the last few days - just happened on this screencast and there was the solution !!
Please give us more of this this type of webcast ..
VB9 is MAGIC - thanks to VB HEAD in the BOX and his colleagues ...
It would be more helpful if the exmaple is with some realistic data. Also, discussion on XSLT complexity and its unfriendliness to developers is understandable but how can we display xml if there are no office clients and how simple is it to build such an xml with all the style elements and spreadsheet format info?
Also the XSD didn't make much sense to me.
Anyway, the expressions are quite a good/new concept. Yet to figure how really simple they are in the real world!
Using the concepts you guys demoed, I was able to create a REST interface for ASP.NET that uses XElement
