WCF Service behaviour default binding settings

Yes, based on binding(basicHttpBinding, wsHttpBinding,netTcpBinding…ect)default values are changed

Default Service behaviours

EX:

We can customize the behaviour of service(called as servicebehaviour). Using InstanceContextMode, ConcurrencyMode settings.

These default values are changed as per bindings.

Demo:

namespace WCFConcurrencyDemo

{

    [ServiceContract]

    interface IConcurrenyDemo

    {

        [OperationContract(IsOneWay = true)]

        void Call(string ClientName);

    }

   //[ServiceBehavior(InstanceContextMode=InstanceContextMode.PerSession,ConcurrencyMode=ConcurrencyMode.Single)]

    [ServiceBehavior]

    class ConcurrencyDemo : IConcurrenyDemo

    {

        public int i;

        public void Call(string ClientName)

        {

            i++;

            Console.WriteLine("Client name :" + ClientName + " Instance:" +

         i.ToString() + " Thread:" + Thread.CurrentThread.ManagedThreadId.ToString() +" Time:" + DateTime.Now.ToString() + "\n\n");

            // Wait for 5 seconds

            Thread.Sleep(5000);

        }

      

    }

}

Hosting the Service:

namespace WCFConcurrencyDemo

{

    class Program

    {

        static void Main(string[] args)

        {

            Uri httpUrl = new Uri("http://localhost:8010/MyService/HelloWorld");

            //Create ServiceHost

            ServiceHost host = new ServiceHost(typeof(ConcurrencyDemo), httpUrl);

            //Add a service endpoint

host.AddServiceEndpoint(typeof(IConcurrenyDemo), new BasicHttpBinding(), "");   // In case of BasicHttpBinding

 host.AddServiceEndpoint(typeof(IConcurrenyDemo), new WSHttpBinding(), "");    

// In case of WSHttpBinding

            //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 <Enter> key to stop");

            Console.ReadLine();

        }

    }

}

Client Consume the service:

basicHttpBinding:

In case of basicHttpBinding per every client call create a new instance of service object.and new threads are created.

WsHttpBinding:

In case of WsHttpBinding per every client call create single instance at first request then 2^nd request onwords utilizes the old service instance.then single thread is created and serve the all the requests.

Finally

For EVERY REQUEST

basicHttpbinding: new instance,new thread------> Percall

wshttpbinding: single instancem single thread--->PerSession.

Demo 2:my another article is BasicHttpBinding(Percall),WsHttpBinding(Persession)

BasicHttpBinding concurrency default is Concurrency is PerCall

default basicHttpBinding:

1111111111

this is wsHttpBinding concurrency default is Concurrency is PerSession

default wsHttpBinding:

12345678910
