According to this post I've just faced with some issue on the log files in %temp%, which indicates that the new Windows Communication Foundation embeded with May 2006 CTP WinFX runtime Components, tries to register the service model configurations and it fails if there isn't IIS installed.

I managed to setup winfxrc.exe on a clean Windows Vista Build 5342 and also installed EID May 2006 CTP and everything went well.
