Custom SOAP message not returned/recieved

Hi,

I am using VS 2008 for creating a sample WS that returns custom SOAP error message. I have created a client that is a win app that should recieve a message but instead of SOAP exception, the Exception block is triggered. why?
here is my server code for exception

Code:

[WebMethod]
        public void GetException()
        {
            try
            {
                int i = 1;
                int j = 0;
                int z;

                z = i / j;
            }
            catch (Exception ex)
            {
                throw RaiseException("GetException", "WSSoapException", ex.Message, "1000", ex.Source, FaultCode.Server);
            }
        }

        public SoapException RaiseException(string uri, string wsNameSpace, string errorMessage, 
                                            string errorNumber, string errorSource, FaultCode code)
        {
            XmlQualifiedName faultCodeLocation = null;
            switch (code)
            {
                case FaultCode.Client:
                    faultCodeLocation = SoapException.ClientFaultCode;
                    break;
                case FaultCode.Server:
                    faultCodeLocation = SoapException.ServerFaultCode;
                    break;
            }

            XmlDocument faultDoc = new XmlDocument();
            XmlNode rootNode = faultDoc.CreateNode(XmlNodeType.Element,
                                SoapException.DetailElementName.Name,
                                SoapException.DetailElementName.Namespace);
            XmlNode wsException = faultDoc.CreateNode(XmlNodeType.Element, "WSException", wsNameSpace);
            XmlNode errorCode = faultDoc.CreateNode(XmlNodeType.Element, "ErrorCode", wsNameSpace);
            errorCode.InnerText = errorNumber;
            XmlNode errMsg = faultDoc.CreateNode(XmlNodeType.Element, "Message", wsNameSpace);
            errMsg.InnerText = errorMessage;
            XmlNode errorSourceNode = faultDoc.CreateNode(XmlNodeType.Element, "ErrorSource",wsNameSpace);
            errorSourceNode.InnerText = errorSource;

            wsException.AppendChild(errorCode);
            wsException.AppendChild(errMsg);
            wsException.AppendChild(errorSourceNode);

            rootNode.AppendChild(wsException);

            SoapException soapEx = new SoapException(errorMessage, faultCodeLocation, uri, rootNode);
            return soapEx;

        }

and on my form side.

Code:

try
            {
                ExceptionRef.Service1SoapClient wsEx = new TestApp.ExceptionRef.Service1SoapClient();
                wsEx.GetException();
            }
            catch (SoapException soapEX)
            {
                MessageBox.Show(soapEX.Code.ToString());
                XmlDocument faultDoc = new XmlDocument();
                faultDoc.Load(soapEX.Detail.OuterXml);
                XmlNamespaceManager nsManager = new XmlNamespaceManager(faultDoc.NameTable);
                nsManager.AddNamespace("errorNS", "WSSoapException");

                XmlNode Node = faultDoc.DocumentElement.SelectSingleNode("errorNS:WSException", nsManager);
                string errorNumber = Node.SelectSingleNode("errorNS:ErrorCode", nsManager).InnerText;
                string errorMessage = Node.SelectSingleNode("errorNS:Message", nsManager).InnerText;
                string errorSource = Node.SelectSingleNode("errorNS:ErrorSource", nsManager).InnerText;
                
                MessageBox.Show("Error Number is " + errorNumber);
                MessageBox.Show("Error Message is " + errorMessage);
                MessageBox.Show("Error Source is " + errorSource); 

            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
