WCF Learning Note (I)

1. How to: Define a Windows Communication Foundation Service Contract

   using System;
   // Step 5: Add the using statement for the System.ServiceModel namespace
   using System.ServiceModel;
   namespace Microsoft.ServiceModel.Samples
   {
     // Step 6: Define a service contract.
     [ServiceContract(Namespace = "http://Microsoft.ServiceModel.Samples")]
     public interface ICalculator
     {
       // Step7: Create the method declaration for the contract.
       [OperationContract]
       double Add(double n1, double n2);
       [OperationContract]
       double Subtract(double n1, double n2);
       [OperationContract]
       double Multiply(double n1, double n2);
       [OperationContract]
       double Divide(double n1, double n2);
     }
   }

A WCF service is a construct that exposes one or more endpoints, each of which exposes one or more service operations. The endpoint of a service specifies an address where the service can be found, a binding that contains the information that a client must communicate with the service, and a contract that defines the functionality provided by the service to its clients.

<client>
      <endpoint
           address="http://localhost:8000/ServiceModelSamples/Service/CalculatorService"
           binding="wsHttpBinding"
           bindingConfiguration="WSHttpBinding_ICalculator"
           contract="Microsoft.ServiceModel.Samples.ICalculator"
           name="WSHttpBinding_ICalculator">
      </endpoint>
</client>
