Binding configuration | WCF Tutorial pdf

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.serviceModel>
 <services>
  <service  name="MyService">
 <endpoint address="http://localhost/IISHostedService/MyService.svc" 
 binding="wsHttpBinding" bindingName="wshttpbind"
contract="IMyService">
 <identity>
 <dns value="localhost"/>
 </identity>
 </endpoint>
 <endpoint address="mex" binding="mexHttpBinding"
contract="IMetadataExchange"/>
   </service>
 </services>
 <bindings>
     <wsHttpBinding>
       <binding name="wshttpbind"  allowCookies="true"
closeTimeout="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.ISimpleCalculator), 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();
