    Did you search the form topics first as there is a thread not 5 threads away from your post that is covering the topic.

  • Hi Sunil404,

    Here is some helpful documentation from MSDN:

    In a nutshell, you will right click your project within the solution and choose "Add Service Reference".  You copy the path to the .svc file into the address box and click "Discover", from there it should connect to your WCF service and allow you to create a service reference to your WCF service.  You can then work with classes and methods exposed by your service.

    Best of luck.

  • Hi Niranjan Kala,

    As far as I know, we can use the  httpwebrequest and httpwebresponse or webclient classes

    in our client to call our service.

    Here is my sample:

    Service code:

            [WebInvoke(Method = "PUT", UriTemplate = "/PutString",
              RequestFormat = WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Xml)]
            string PutString(string value);
            [WebGet(UriTemplate = "GetSampleMethod/inputStr/{name}",ResponseFormat=WebMessageFormat.Json)]
            string GetSampleMethod(string name);


     public string PutString(string value)
                return value += "..PutString get called";
              public string GetSampleMethod(string strUserName)
                StringBuilder strReturnValue = new StringBuilder();
                // return username prefixed as shown below
    		    ("You have entered userName as {0}", strUserName));
                return strReturnValue.ToString();

    Client Code:

      static void PutMethod()
                string ServiceUrl;
                ServiceUrl = @"http://LocalHost:7789/MySericeDemo/";
                WebClient WC = new WebClient();
                WC.Headers["Content-type"] = "application/xml";
                MemoryStream MS = new MemoryStream();
                DataContractSerializer JSrz = new DataContractSerializer(typeof(string));
                string NAME = "ABC";
                JSrz.WriteObject(MS, NAME);
                byte[] res1 = WC.UploadData(ServiceUrl + "PutString", "PUT", MS.ToArray());
                MS = new MemoryStream(res1);
                JSrz = new DataContractSerializer(typeof(string));
                string result = (string)JSrz.ReadObject(MS);
            static void CallGetMethod()
                string url = "http://LocalHost:7789/MySericeDemo/GetSampleMethod/inputStr/suryaprakash";
                string strResult = string.Empty;
                HttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create(url);
                webrequest.Method = "GET";
                webrequest.ContentType = "application/json";
                HttpWebResponse webresponse = (HttpWebResponse)webrequest.GetResponse();
                Encoding enc = System.Text.Encoding.GetEncoding("utf-8");
                StreamReader loResponseStream = new StreamReader
    				(webresponse.GetResponseStream(), enc);
                strResult = loResponseStream.ReadToEnd();


    Hope it helps.

  • WCF and REST are different things. For a WCF service, you should generate a Service Reference.

    For a REST service aka. Web API, you can use a Rest Client like RestClient.Net.

    Some samples:


    With Newtonsoft serialization

    varclient=newClient(newNewtonsoftSerializationAdapter(), newUri(""));

    With default serialization on .NET Core

    var client = new Client(new Uri(""));
    var response = await client.GetAsync<List<RestCountry>>();

    Protocol Buffers (Binary)

    var person = new Person { FirstName = "Bob", Surname = "Smith" };
    var client = new Client(new ProtobufSerializationAdapter(), new Uri("http://localhost:42908/person"));
    person = await client.PostAsync<Person, Person>(person);


    var client = new Client(new NewtonsoftSerializationAdapter(), new Uri(""));
    UserPost userPost = await client.PostAsync<UserPost, UserPost>(new UserPost { title = "Title" }, "/posts");


    varclient=newClient(newNewtonsoftSerializationAdapter(), newUri(""));
