Microsoft has started to create awareness on Indigo. Watch the video of Eric Rudder and Ari Bixhorn's keynote presenting Indigo at VSLive.
Rocky Lothka reports on Eric Rudder's keynote: Indigo: the future of asmx/wse/es/msmq/remoting.
Mujtaba Syed has a number of posts on Indigo from VSLive:
Sam Gentile asks us in his Indigo Unleashed post to remember the ABC's of Indigo: Address, Binding, Contract. He also promises to post some code samples later on.
And Clemens Vasters shows us with an Indigo "Hello World" example how intuitive the programming model is. Have a look at the Indigo Server code.
I'm looking forward to get my hands on the Community Technology Preview (CTP) of Longhorn's "Indigo" communications subsystem (along with a Avalon CTP2) by the end of March.
