One of the new features in the .NET Framework 3.5 SP1 is ADO.NET Data Services. This enables you to expose the contents of a data source, e.g. a SQL Server database, through something that looks roughly like an RSS feed, accessed in a similar manner to a web service. That’s nice but why do you care as an IT pro? Well, it’s a convenient way of making the contents of the MDT database available to programs or scripts without forcing them to use ADO to access SQL Server directly.
