Accessing WCF service without creating Proxy

Each time when we want to consume a WCF service, we need to create proxy at client side. To create proxy, service must expose metadata endpoint.

Normally

We create a WCF service
Expose metadata endpoint
Add service reference at client side to create the proxy.
Using the proxy calls the service operation contracts.
Normally we call the service as

MyServiceContractClient proxy = new MyServiceContractClient();
var res = proxy.GetData(9);
console.WriteLine(res);
console.ReadKey(true);

Let us assume we want to call the service using channel without creating proxy or adding the service reference. We need to follow the below steps

Step 1

Put all the DataContract or ServiceContract in a separate DLL or class library. Add the reference of System.ServiceModel in class library. And create the service contract as below,

MyServiceContract.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;

namespace ContractDll
{
 [ServiceContract]
   public  interface MyServiceContract
   {
     [OperationContract]
     string GetData(int value);
   }
}
