Is there any good material about the working mechanism of IIS hosting WCF web service?

It's not really magic - it's metadata exchange! :-).

As marc_s stated, the "Add Service Reference" button runs a tool that collects the metadata from the service, and generates client code from it.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
