Binding configuration -- Binding

      Binding can be configured either through configuration file or Programming. Let us see the binding representation in each method

Administrative (Configuration file):  

        In the configuration file of the hosting application, you can add the <bindings> element inside the <system.serviceModel> element and add the properties to particular binding type. Properties corresponding to the particular binding type can be mentioned below. Name of the binding properties that you are going to use has to be mention in the end point.

<system.service Model>


<Services>

 <service name="MyService">   

 <endpoint
address="http://localhost/IISHostedService/MyService.svc"    

Binding="wsHttpBinding" binding Name="wshttpbind"  contract="IMyService">

<Identity>           

<dns value="localhost"/> 

</identity>

</endpoint>

<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>

 </service>

  </services>

  <Bindings>

      <WsHttpBinding>       

<binding name="wshttpbind” allow Cookies="true" close Timeout="00:01:00" ReceiveTimeout="00:01:00"/>     

</wsHttpBinding>

  </bindings>

</system.serviceModel>

Programming Model:

       

      In the following code, I have created the WSHttpBinding object and assign the properties which to be configured. This binding object is added to the Service endpoint for client communication. Similarly you can also create any type of binding and add to endpoint.
          

            //Create a URI to serve as the base address
               Uri httpUrl = new Uri("http://localhost:8090/MyService/SimpleCalculator"); 
            //Create ServiceHost  
        ServiceHost host =new ServiceHost(typeof(MyCalculatorService.SimpleCalculator), httpUrl);              //Create Binding to add to end point  
             WSHttpBinding wshttpbind = new WSHttpBinding();
             wshttpbind.AllowCookies = true;
             wshttpbind.CloseTimeout = new TimeSpan(0, 1, 0);
             wshttpbind.ReceiveTimeout  = new TimeSpan(0, 1, 0);
             //Add a service endpoint
             host.AddServiceEndpoint 
             (typeof(MyCalculatorService.ISimpleCaculator), wshttpbind, "");
             //Enable metadata exchange  
             ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
             smb.HttpGetEnabled = true;

           host.Description.Behaviors.Add(smb);          
             //Start the Service
             host.Open();
             Console.WriteLine("Service is host at " + DateTime.Now.ToString());
             Console.WriteLine("Host is running... Press  key to stop");
             Console.ReadLine();
 

Note: It is always good if you configure the binding properties using configuration file, because 
while moving to the production you no need to change in the code and recompile it. It is always
good practice to represent in the configuration file.
