Now I could be completely wrong, but I've always seen WCF as a development aid while SCA is a design and deployment aid. What I mean by this is that WCF makes the job of consuming and developing individual technology (.NET) services much simpler (especially consumption) but SCA focuses on pan-technology services (BPEL, Workflow, Rules, EJB, WS, etc) both in terms of design and consumption. So WCF makes it easier to abstract the protocols away and do simpler service to service communication, WCF is a developer focused technology that helps make code simpler. SCA however makes it easier to design, deploy and manage enterprise class service solutions, SCA is an architect and operation focused technology that helps make projects simpler.
From a historical point SCA was first released in IBM Process Server which
debuted in 2005, so wasn't "keeping up" with WCF which wasn't released until .NET 3.0. On 18/04/07, Eric Newcomer <[EMAIL PROTECTED]> wrote:
Nothing has happened with it so far at OASIS. Also I believe one of the motivations for SCA was to keep up with WCF...

I wonder what this is referring to - what would qualify as the .NET equivalent to SCA and SDO? Not that I'm a big believer in these two specs, just curious.
