Great article! Thanks!

Little hint for .NET developers:

New .NET wrapper types SqlHierarcyId, SqlGeography, SqlGeometry are not stored in System.Data.dll but in "Microsoft.SqlServer.Types.dll" in "c:\Program Files\Microsoft SQL Server\100\SDK\Assemblies\" directory. After adding the reference to your project you can find them in namespace "Microsoft.SqlServer.Types".
