How to generate a Proxy at runtime?

yes, Proxy generation is done through adding service reference at client which generates proxy at client as xml files(which are platform-operatingsystem/technology-java,php,.net);

proxy generation is not new in wcf. We already know asp.net web service comsuming through

AddWebReference  : http://localhost:72/Service---asp.net webservice/wcf also

or

ServiceReference : http://localhost:72/Service-->wcf

Once service is running then client can consuming in 2 ways

1.  Proxy generation at client

webreference/servicereference

(which are platform-operatingsystem/technology-java,php,.net)

Prepare Service single service with 3 endpoints:

Contract /service define

[ServiceContract(Name="ourservice")]

    //[ServiceContract(Name="OUrService",ProtectionLevel=ProtectionLevel.EncryptAndSign)]

    interface IMathService

    {

        [OperationContract]

        int GetSum(int a, int b);

       

    }

Service implementation:

   class MathService: IMathService

    {       

        public int GetSum(int a, int b)

        {

            return a + b;

        }

    }

Host the service:

static void Main(string[] args)

        {                      

           using (ServiceHost sh = new ServiceHost(typeof(MathService), new Uri("http://localhost:72/Service")))

           {

                //Adding the endpoints to the ServiceHost

sh.AddServiceEndpoint(typeof(IMathService), new NetTcpBinding(), "net.tcp://localhost:71/Service");                            

sh.AddServiceEndpoint(typeof(IMathService), new WSHttpBinding(),"/wsaddress");

sh.AddServiceEndpoint(typeof(IMathService), new BasicHttpBinding(), "/basicaddress");

//Creating a new Service Behavior

           

ServiceMetadataBehavior metadataBehavior = new ServiceMetadataBehavior();

metadataBehavior.HttpGetEnabled = true;

sh.Description.Behaviors.Add(metadataBehavior);

                //Opening the ServiceHost for incoming connections

sh.Open();

                

Console.WriteLine("I am listening ........\n");

Console.WriteLine("Waiting for clinet requests..");

Console.ReadLine();

                //Close opened ServiceHost object

               

            }

        }

Note: serviceHost is a type in System.ServiceModel namespace.which can host ourservice.

In Every Hosting type :

Which can be Self-Hosting.

Which can be IIS-Hosting.

---- ServiceHost---à IS Maindatory type.

Yes service is ready.

No consume the service at client

1.       Design time Proxy:

àAdd service reference.// automatically generated by svcutil.exe tool

And generated configuration of 3 endpoints implements at service.

and

app.config contrains endpoints details

like

binding, endpoint details.

but keep in mind : which also generates a channel/ from  proxy at rumtime.

for their apporiate details.

and

we can browse service is hosted as self-host address of basic/ ws -http binding.

once---

at client :

proxy.GetSume(14,51)--->go to definication-->

step throw Proxy: Reference

another way to generate proxy at desige time is using 

svcutil.exe  tool
go to visual studio 2008/ 2010 commandpromt the 
write command as 
svcutil.exe : address of running service

path
C:\Program Files\Microsoft Visual Studio 9.0\VC\

2.       Runtime Proxy:

 yes, client doen't know about proxy even also can consume the service through as per client has to specify the binding

and contract and address details 

which prepares a proxy---> runtime. but the 

SERVICE HAS these Details exactly.

yes proxy is generated at code like

below:

yes above code generates a proxy at runtime.
