I've create a Project which Host WCF Services it is with EF 6.1 , DevArt Oracle Connector, Unit. I'm able to run this project And Ny *.svc URL is also working. Now I Tried to Use this service in my Prism 4.1 Silverlight Project This is also communicating with this wcf project.
But when I try to get data in 1 module of my App I'm getting this error:
Please guide where I'm going wrong?

when I Prism Module Try to Load data from the WCF Hosted Project.
and at Prism UI project I'm getting

this.container.RegisterType<UserWcfService>(

And in ViewModel Use :
IEventAggregator _eventAggregator;
UserWcfService _Userservice;
public TabViewModel(ITabView view, IEventAggregator eventAggregator , UserWcfService service)
: base(view)
{
_eventAggregator = eventAggregator;
_Userservice = service;

var a=_Userservice.EndgetAllUser(ar);
_UserDetailsDataGridContext = a;
}
Don't know where I'm Going wrong.
