TechEd: Intro to Indigo

Ari Bixhorn gave a great overview of Indigo at the MVP Summit today. The session was very short (only 30 minutes), so not everything was covered, but here are my notes:


Indigo is a response to customer requests for:



  • Security

  • Interoperability

  • Service Oriented Architecture

  • And the question “What API should I use?”

Indigo offers 3 value propositions:



  • Productivity

    • Unification of the existing technologies (remoting, enterprise services, ASMX, etc.)

    • Attributes and configuration – although all NEW work is configuration-based, don’t want to have to recompile code for minor config changes

    • Visual Studio 2005 – the target audience for Indigo, “Whidbey developers”

  • Interoperability

    • WS-* Architecture

    • Investment protection – backwards compatible

  • Service-Oriented Development

    • Evolutionary, not revolutionary

    • Four tenets article by Don Box

So, what’s new in Indigo lately?



  • Beta 1 RC is available – “It’s a feature complete version for Beta 1″ – if you don’t think that’s funny, what’s wrong with you??

  • Peer channel – the peer channel is a mesh of nodes, the mesh rearchitects itself based on the addition/removal of nodes, and after a peer connects to the mesh, the mesh removes itself from activity and the peer connects directly with other peers

  • Indigo User Group Tour – coming soon!

  • Beta 1 for Indigo (the real Beta 1, not the RC of Beta 1) is coming in “Summer, 2005″

  • Indigo will be deployed into production at the same time as Longhorn, although it will be available on Longhorn, Windows Server 2003, and Windows XP (the last 2 as an additional download)
