Introduction to DataSets
Paul Stovell brings us the first episode of his new screencast series, "Binding Patterns", entitled "Working with DataSets". This is a great introduction to the concept of DataSets in ADO.NET, including typed DataSets. It goes for a little over an hour, but I found that it's quite watchable at 1.2 or 1.4 times normal speed, so you can race through it and still pick everything up.
If you're new to .NET and want to get into some database programming, this would be a great place to start!
Also, check out the comment I left on his post regarding the initialization of default field values in DataSets. The solution that Paul gives in the screencast works well, but it's worth knowing a few different approaches to the same problem.
