I've been spending some free time getting back up to speed on Indigo because (a) it is quite interesting, and (b) has big implications for BPI solutions moving forward. I've added a VS.NET 2005/Indigo machine to my BizTalk farm and want to see how I can get the BizTalk Servers to play nicely with it.
However, sometimes I have serious brain cramps while setting things up, and today is no exception. Wasted like 10 minutes figuring out why my Indigo *.svc file wouldn't get processed by IIS. I then realized that the *.svc extension probably wasn't mapped within IIS. I had assumed that the Indigo install would have done that for me. Luckily I found this article (see Host the Web Service in IIS section) which reminded me of the steps necessary to get things back on track.
