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)
Welcome back to the "Developer, Meet Server" screencast everybody

In this screencast we will dive back into Transactional NTFS and look at how you can use it with WCF to build powerful transactional capabilities into a service-based system.

It was marked with the auto-complete attribute that votes to commit the transation if no exceptions occur. What effect does that have in this case?
The client has to issue the commit in this scenario. Is the work performed by the service still uncommitted at the period of time "after the service method completes and before the commit button is clicked"? I suspect yes, so why have that attribute on the method? Is it just to play nice in case this service is invoked by a different type of client?
I went ahead and tested it without it and you are right, it is not necessary. So, thanks for pointing that out
When I test the TxF/WCF demo on the Longhorn Dec CTP I get following error during the method 'CreateFileTransacted' :
===============
The Transaction object already has a superior enlistment, and the caller attempted an operation that would have created a new superior. Only a single superior enlistment is allow.
===============
Win32Error : 6709.
Any idea what I should do to get the demo working?
Thanks in advance.
