Hi, 

I have created the Two Methods one is to Get and Another one is to Create,

For Getting the Data is working fine , but when i trying to post the Data is showing the Error like " Method not Found(404)"

The Code is as following.

Contract Methods :

public interface IContactPositionService    {
[OperationContract]
[WebInvoke(BodyStyle = WebMessageBodyStyle.Wrapped, Method = "GET", RequestFormat=WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "GetContactPositionList")]
List<ContactPosition> GetContactPositionList();
[OperationContract]
[WebInvoke(Method = "PUT", BodyStyle = webMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "AddContactPosition")]
int AddContactPosition(ContactPosition position);}

And Corresponding Serivice class is like :

public class ContactPositionService : IContactPositionService
   {
 public List<ContactPosition> GetContactPositionList()
       {
           DataSet ds = clsObj.GetContactPositionsList();
           return ConverterHelper.Convert<ContactPosition>(ds.Tables[0]);
       }

public int AddContactPosition(ContactPosition position)
       {
         //  throw new System.NotImplementedException();
       }

And in Web.config file i have configured the End Points As :

<services>
      <service name="VirtusMobileService.ContactPositionService" behaviorConfiguration="VMS.Position.ServiceBehaviour">
        <endpoint address="" behaviorConfiguration="VMS.Position.EndPointBehaviour"
          binding="webHttpBinding" bindingConfiguration="" name="VMS.Position.EndPoint"
          contract="VirtusMobileService.IContactPositionService" />
        <endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
      </service>
    </services>
    <behaviors>
      <endpointBehaviors>
        <behavior name="VMS.Position.EndPointBehaviour">
          <webHttp helpEnabled="true" />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="VMS.ServiceBehaviour">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
        <behavior name="VMS.Position.ServiceBehaviour">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>

    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

From the Client Asp.net page we call the Services for adding the Contact person object as like below :

<pre lang="c#">
private void AddData()
        {
            string sURL = "http://localhost:51293/ContactPositionService.svc/AddContactPosition";       
            ContactPosition order = new ContactPosition
            {
                PositionCode="10550",
                PositionFinbaseId=11,
                PositionTitle="Manager"
            };

            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(ContactPosition));
            MemoryStream mem = new MemoryStream();
            ser.WriteObject(mem, order);
            string data = Encoding.UTF8.GetString(mem.ToArray(), 0, (int)mem.Length);
            WebClient webClient = new WebClient();
            webClient.Headers["Content-type"] = "application/json";
            webClient.Encoding = Encoding.UTF8;
            webClient.UploadData(sURL, "PUT", mem.ToArray());         // Here it is showing Error
             Console.WriteLine("Order placed successfully...");  

}

While it comes to , " uploadData " it is showing error like  "  remote server returned an error: (404) Not Found."

   If i am trying to Get the Data using the   "GetContactPositionList" it showing the data Correctly , but when i am trying to work with "PUT" method it is showing that error.

I tested the url in Fiddler , it is showing the same error in Response Header "HTTP/1.1 405 Method Not Allowed" and in text viewer it showing like below

<div id="content">
      <p class="heading1">Service</p>
      <p xmlns="">Method not allowed. Please see the <a rel="help-page" href="http://localhost:51293/ContactPositionService.svc/help">service help page</a> for constructing valid requests to the service.</p>
    </div>

Please Suggest the answer.

Thanks.
