Hosting WCF Service in IIS w/ Windows Authentication
I can't believe I wasted 10minutes on something that should be the simplest ever.
You might encounter an exception when trying to host a WCF service in IIS with windows authentication where it would say the IIS isn't configured with windows auth so the service itself can't be configured with windows auth.
I had that exception.
The problem is that the IIS vdir was configured with windows auth! and it still blew up.
After a quick searching, I found this post which did the trick.
So.. if you do encounter this, I hope I saved you some time.
