Hmm...I thought it was kind of odd that Visual Studio didn't support intellisense for WCF configuration elements (but then again, I've kind of become intimately familiar with the core elements without having the schema).
Turns out that you have to take care of it manually by updating the schema file for configuration.
Helps configuration go much more smoothly until Orcas arrives.
I'm surprised that this hasn't been posted across more blogs since it seems like a big, big bonus to have this for developing WCF applications. Is it common knowledge? Was there an SP that updated the schema files? I know that installing .Net 3.0 didn't change the configuration files on my system at least.
