Our Restful Service
Contract

[ServiceContract]
    public interface IOrionChatService
    {


 [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare,ResponseFormat = WebMessageFormat.Json, UriTemplate = "/PushNotification")]
        [OperationContract]
        void MyServiceMethod(PostedInformation postedInformations);
}

  public void MyServiceMethod(PostedInformation postedInformations)
{
//do implemention code here
}

DataContract

  [DataContract]
    public class PostedInformation 
    {
        [DataMember]
        public List<string> To { get; set; }
        [DataMember]
        public string SenderEmail { get; set; }
        [DataMember]
        public string Subject { get; set; }
        [DataMember]
        public string SenderFullName { get; set; }

    }


Calling our created Restful service from a Console application using HttpWebRequest

//Create a  new object of the class that we want to post

  PostedInformation postedInformations = new PostedInformation ()
            {
               SenderEmail = "aaa@bbb.com",
               SenderFullName = "test",
                To = new List<string>() { "ccc@eee.com" }
            };
//Serialize the postedInformations to jSon using Newtonsoft.json. You can download dll from here //http://json.codeplex.com/



 var dataToSend = Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(postedInformations ));
//Passyour service url to the create method
            var req = 
HttpWebRequest.Create("http://localhost/MyServer/YourServiceName.svc/MyServiceMethod");
            req.ContentType = "application/json";
            req.ContentLength = dataToSend.Length;
            req.Method = "POST";
            req.GetRequestStream().Write(dataToSend, 0, dataToSend.Length);
            var response = req.GetResponse();
