The audio level is very low for this video. Running Silverlight 3.0.40818.0 on Win 7 RTM. The volume indicator in the Windows Volume Mixer barely moves beyond 5% when volume is fully cranked up in the Silverlight player and for IE in the Volume Mixer.
Last Friday a Channel9 video appeared with Anders Hejlsberg and Sam Drucker talking about LINQ and Entities. They talk about raising the level of abstraction for programmers when programming against data. Anders
makes a very good point at 6m42s that LINQ adds a level of abstraction without taking away capabilities at the bottom level (like writing your own SQL query). The loss of capabilities at the bottom often happens when the level of abstraction is being raised.
Anders says: “We are very conscious of not sliding the spectrum up but growing the capabilities.”
At the end of the video (at 21m58s) we get a glimpse into the reason behind the
retraction of the MSDN Article called
Next-Generation Data Access: Making the Conceptual Level Real which was also about this subject. Microsoft was working on two parallel tracks (ADO.NET vNext and LINQ) on different
teams and is now struggling with realigning those efforts.
