The Dutch Microsoft .NET magazine #22 (September 2008) contains an article I have written an Introduction to the SQL Server 2008 HierarchyID Data Type. You can download the complete source of the article here. In this source I also fixed the problem with the IsDescendant() method. This method was renamed in RC0, my article was based on a Beta. The method is renamed to IsDescendantOf() and the argument has also changed.
