Problem with MS WCF Message Inspector sample

Question

I am trying to use the MS Message Inspector sample from WCF Message Inspector

I converted the project to VS2010 and added a WCF application with a svc class. However, when I try to add a service reference, I am getting the following error:

Could not find a base address that matches cheme http for the endpoint with binding WSHttpBinding. Registered base address schemes are []

I suspect the issue to be related to config files. I would appreciate any help. Here is the web.config from WCF application:
