Just spotted this on Michael Swanson's blog from Monday 10/24/2005: The session content from last month's Microsoft Professional Developers Conference 2005 (PDC05) is now available online at microsoft.sitestream.com/PDC05/. You can watch the session videos online and/or download the video and slides for offline viewing. There's a huge amount of content here, but it's only going to be available for six months. The site requires Internet Explorer 5.5 or better.
Side note: At my session on Integrating RSS with Visual FoxPro Applications at Southwest Fox 2005 earlier this month, I mentioned Microsoft is working on RSS features for Vista and IE7. In the PDC05 materials I found session DAT320: Windows Vista: Building RSS Enabled Applications, which provides some insight into Microsoft's plans in this area. The session runs just over an hour and fifteen minutes and is well worth watching if you're interested in the future of RSS as Microsoft sees it.
