Um quite new to WCF . I think I have messed up a bit. So this is what I did so far and I ve hosted my WCF service in IIS
First the Contracts
using System
Set the service endpoint address to just the service filename (this is the relative part):
address="Service1.svc"
or set the address to blank for each endpoint (I don't think its needed when hosting in the development environment or in IIS)
address=""
See this answer to another question
The relevant part is:
the virtual directory (in IIS) where your *.svc file exists defines your service endpoint's address.
