It looks like the infamous ADO.NET vNext articles try to rear their head again on MSDN. They were taken down before. I just noticed they reappeared in the RSS feed for Visual Studio. At the moment they are also announced on the Visual Studio 2005 page on MSDN, because this page shows the newest items on this RSS feed.
But guess what, the links are dead. So you are still not able to read these articles. There is no official word from Microsoft about what is going on with these articles.
Below you see a screenshot of part of the RSS feed as rendered by Firefox. Just to prove I didn't see ghosts in case these items also disappear from the RSS feed 🙂
