Here is a new video Peter Hallam and I shot in his office. We started off talking about a new feature called automatic properties that will be part of the Orcas release of Visual Studio. The discussion then turns to the history and evolution of the C# language. We briefly cover the exciting time when Peter worked with Anders Hejlsberg and others to shape the C# language. Near the end of the video, the discussion turns to LINQ in general, and extension methods in particular. In this last section, Peter has a chance to explore some simple ways you can use extension methods to enhance the use of interfaces in your programs.
