        {
            return (obj.a + obj.b); 

        }

    }
    public class abc {
        public int a { get; set; }
        public int b { get; set; }

        }

        }
}

I wish to learn, how can i make call to this wcf ria service at the mainPage at the silverlight?

Answer 1

You can call your service on silverlight side this way:

DomainService1 domainService = new DomainService1();
domainService.sum1((op) => 
{
    //op.Value has the result
}, null);

or

DomainService1 domainService = new DomainService1();
domainService.sum1(Sum1Completed, null);

(...)

void Sum1Completed(InvokeOperation<int> op)
{
    //op.Value has the result
}
