I get more impressed with Indigo with each passing day. Besides being quite long, the latest episode of the .NET Show discusses how Indigo came about and what it is attempting to accomplish.
In this episode of the .NET Show John Shewchuk discusses how "Indigo" applies to the architecture of the applications you are designing today, and how it will become a core component of the applications you are planning on developing for Longhorn. Steve Swartz then walks us through some code examples to illustrate the programming model for "Indigo", and how easy it is to add support for its various features into your applications.
In addition, if you pay attention to Erica's open segment, you will get to see my name on the show (yes, I am lame :)
