I want to access all the methods exposed in the service through the URL. if suppose the URL will be :


How can I access methods:

  1. if suppose I have a ServiceReference
  2. and what should I do if don't have the Service Reference.

In order to use a WCF service, you will need to create a WCF client proxy.

In Visual Studio, you would right-click on the project and pick the "Add Service Reference" from the context menu. Type in the URL you want to connect to, and if that service is running, you should get a client proxy file generated for you.

This file will typically contain a class called MyServiceClient - you can instantiate that class, and you should see all the available methods on that client class at your disposal.

If you don't want to add a service reference in Visual Studio, you can achieve the same result by executing the svcutil.exe command line tool - this will also generate all the necessary files for your client proxy class for you.


UPDATE: if you want to initialize a client proxy at runtime, you can definitely do that - you'll need to decide which binding to use (transport protocol), and which address to connect to, and then you can do:

BasicHttpBinding binding = new BasicHttpBinding();
EndpointAddress address = new EndpointAddress("http://localhost:8888/MyService");

MyServiceClient serviceClient = new MyServiceClient(binding, address);

But even in this case, you need to have imported and created the proxy client first, by using the "Add Service Reference" or svcutil.exe tools.

Call the Url of WCF Service Methods - MSDN, But now im trying to acces the services from non Silverlight applications, /​1193124/how-to-consume-wcf-web-service-through-url-at-run-time. I have an requirement where I have to consume WCF(svc) services in my application dynamically, i.e. I will have a textbox in my application where the user enters the URL of the service and hits a button which will make my service consumable in my application. I will list out the methods of the service on the screen.

To answer how to do it without having a service reference. Have a look here (option #a):

Writing your first WCF client

You still need some reference (namely a reference to an assembly containing the contract / interface) but you do not make a service reference.

EDIT: Though the above is possible I would not recommend it. Performance is not exactly great when you have to generate the proxies like this. I usually use svcutil.exe and create an assembly containing my clients and create a reference to that assembly. This way you have more options for controlling what the proxies look like.

Dynamically consuming WCF Service from Service URL or WSDL , I hope the services publish metadata, or I suspect the answer will be 'you can't'. Perhaps this might help: Step 1 − Once a service is hosted in IIS, we have to consume it in client applications. Before creating the client application, we need to create a proxy for the service. This proxy is used by the client application to interact with the service. To create a proxy, run Visual Studio 2008 command prompt.

You can also make use of the WebClient class to call the WCF service without needing a service proxy. Effectively you can send and receive Strings and Binary data and also simulate POSTs.

I use it extensively for reusable components where the developer may not ever create the required proxy methods. A good comparison of ways to do POST is available here.

You call it with a /functionname, eg:



How do you configure your method in the WCF service so you can call it directly from the browser?

I have an Interface:

public interface IWebServiceImpl
    [WebInvoke(Method = "GET",
        ResponseFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Bare,
        UriTemplate = "GetVersionNumber")]
    string GetVersionNumber();

And a class to implement the GetVersionNumber method in the Interface:

public class WebServiceImpl
    public string GetVersionNumber()
            return ""; //In real life this isn't hard-coded

Finally here is the Web.config configuration:

      <messageLogging logEntireMessage="true" logMalformedMessages="false" logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="false" maxMessagesToLog="3000" maxSizeOfMessageToLog="2000"/>
        <binding name="webBinding">
          <security mode="Transport"/>
      <service behaviorConfiguration="ServiceBehaviour" name="YOURWebServiceNameSpace.WebServiceImpl">            
        <endpoint address="" behaviorConfiguration="web" binding="webHttpBinding" contract="YOURWebServiceNameSpace.IWebServiceImpl"/>
        <behavior name="ServiceBehaviour">
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        <behavior name="web">

How to Create and Consume WCF Services, WCF provides a runtime environment for your services, enabling you to expose CLR Net Remoting, MSMQ, Web Services and COM+ technologies. Runtime​.Serialization;; using System.ServiceModel;; using System. "Add Service Reference" and paste copied URL in Address section of "Add Service  A proxy must be generated to consume a WCF service, which allows the application to connect to the service. The proxy is constructed by consuming service metadata that define the methods and associated service configuration. This metadata is exposed in the form of a Web Services Description Language (WSDL)

You can just provide the wsdl of your service: http://localhost/MyService/MyService.svc?wsdl.

From wsdl you can generate proxy classes and use them on the client.

Change Web service reference at run time, Please see my case below: Web service Reference 'URL Behavior. WCF client proxy (created via "Add ServiceReference") to consume the  With the service running, right click the project that will contain the WCF client proxy and select Add > Service Reference. In the Add Service Reference Dialog, type in the URL to the service you want to call and click the Go button. The dialog will display a list of services available at the address you specify.

WCF the Manual Way… the Right Way, Two are web related; both are called "WCF Service" and do pretty much the same thing. Runtime.Serialization; An interface-based service contract; A service class Since I will not be using the same technique to consume a service this time be the URL corresponding to the deployment location of this web application,  I will explain how to consume these services through SSIS package in my next article. Let’s say we have one Web Service running in IIS and it exposes the ProcessData() method. It does some business functionality internally and sends the details to a third party service.

Runtime.Serialization;. using System.ServiceModel;. using System. Please make sure, that you will only be able to let your friend consume your WCF application if he can access that URL from his network too; if he's using the same network then you can give him localhost URL too, but if he will be accessing through some other network, then you will have to purchase a static IP address and you will have to

Web endpoints send data by XML or JSON, there is no SOAP envelope. This topic demonstrates how to expose such an endpoint. The only way to secure a Web endpoint is to expose it through HTTPS, using transport security.

  • Please clarify your question. I can't tell what you want to accomplish. Do you want to be able to call the methods, or do you want a list of them?
  • John I want to access methods..Acutally I want to consume the web service through URL.
  • And why not use the service reference?
  • How can I specify the binding address and remote address while initializing the service client .. Please excuse me for the obvious question
  • Hi Marc, Thanks for you answer. I am doing the same and able to access . But my requirement is to provide the same interface (as we get when we right click to add the service reference) to client in which he can see the urls and service reference will be updated accordingly with url selected.
  • How can I acheieve this at run time. How to construct the serviceclient at runtime with the URL selected.
  • OK, so you want to let your client add service references at runtime? What is he going to do with them? I mean - you can certainly create a proxy at runtime - but how will he or you be calling methods?
  • One thing you can do e.g. for testing is use some tool like SoapUI ( - this allows you to dynamically discover, connect to, and execute SOAP calls - but that's really not your app anymore - just a debug/test front-end for your services. Is that what you're looking for?
  • Can I intialize the Serviceclient. I see it has 5 constructors taking endpoingBindingaddress and remoteaddress. can you please tell me what are they and how it can be intialized..
  • I have tried your approach without luck. How do you configure your method in the wfc service so you can call it directly from the browser?
  • @Örvar see edit, if that doesn't help post a new question.
  • Thanks alot for your answer, appreciate it. We have however abandoned the idea here at work using our existing wcf service. Going to setup a rest api, makes more sense for our further requirements
