How was Indigo used in pre-reset Longhorn builds?

[Emir214]

Indigo (now the open-source Windows Communication Foundation) was promoted as one of the pillars of Windows Longhorn. But I cannot find any source saying how Indigo was used in pre-reset Longhorn builds.

Compare this with Avalon (see longhorn.ms discussions on APIs and the UI) and WinFS (see BA Wiki article under construction).

A quick google search returns this, saying that it was designed to make apps able to communicate with each other using XML, but I have no way of determining if this is correct.

Thanks for the links, _furokku. They explain how Indigo works, but not how it was used in Longhorn. But the second link is promising. From https://redmondmag.com/articles/2004/02 ... layer.aspx

The initial release of Longhorn is a client operating system, but the new Indigo features won't be too interesting if they are available only on client machines. They also need to be available on the server machines the clients interact with. To that end, Microsoft has also announced that key portions of the Indigo/WSE 2.0 specification will be available for Windows Server 2003. —Kathleen Dollard

Maybe builds 4028 and 4066 have features that used Indigo.
