I just released three more LINQ how-to videos, #3, #4 and #5 and they're up on the Developer Center now. One is an example of how to use LINQ to DataSets and the other two focus on LINQ to SQL and the new O\R designer.
If you're thinking about converting your Visual Studio 2005 apps to Visual Studio 2008 and are using DataSets right now, you'll want to take a look at the LINQ over DataSets video. You don't have to re-architect your applications in order to take advantage of Language Integrated Query right now. There is a built-in LINQ over DataSet provider that allows you to write queries right over your current DataSets.
But why stop there :-) ?
LINQ to SQL is a built-in infrastructure that allows you to create object models directly from tables in your SQL databases and use them in your Visual Basic applications. These objects can be custom business objects that you extend with partial methods or even inherit from your own base class. And best of all, LINQ to SQL manages changes in these objects for you automatically, and it can be as easy as using a DataSet. If you're creating new data-based applications or looking at upgrading and extending your current ones, this is a technology that you won't want to miss. So get on learning it now by watching these videos.
Also please feel free to rate the videos and send me feedback by clicking on the stars in the right-hand side of the landing pages (on a scale of 1 to 5 stars, 5 being the best). I actually do read all of them and so do our site managers!
