Thank you for your reply. I have been trying to get SOAP::Lite to work with my WCF Windows Service and all my efforts have been unsuccessful. Could you please tell me what I am doing wrong? My APP.CONFIG file in C#/XML looks like this:

And my C# Interface looks like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using Company.Department.Project.BusinessEntities;
using Company.Department.ProjectB.BusinessLogic;
using Company.Department.ProjectB.BusinessEntities;

namespace Company.Department.Project.WCFService
{
    [ServiceContract(Name = "Company.Department.Project.WCFService.Pro
+jectService", Namespace = "http://projectservice.department.company.c
+om/")]
    public interface IProjectService
    {
        [OperationContract(Name="GetWorkOrderList")]
        List<BEWorkOrder> GetWorkOrderList(string siteId);

        [OperationContract(Name="GetWorkOrder")]
        BEWorkOrder GetWorkOrder(string woName, string siteId);

        [OperationContract(Name="ReturnStatus")]
        string ReturnStatus();
    }
}

And the PERL CODE I have looks like this:

#!/usr/bin/perl -w
use strict;
use SOAP::Lite;

my $url = 'http://MYSERVER-NAME:8732/Company.Department.Project.Projec
+tService.ProjectService/?wsdl';
my $uri = 'http://tempuri.org/';
my $xmlns = 'http://tempuri.org/';

# Setup Network Connection

my $soap = SOAP::Lite
    -> uri($uri)
        -> on_action(sub{sprintf '%sIProjectService/%s', @_})
    -> proxy($url);
    
my $response = $soap->GetWorkOrderList(SOAP::Data->new(name=>'siteId',
+ value=>'BKK'));
        

if($response->fault){
    die $response->faultstring;
}
else{
    print $response->result;
}
[download]

The error that I get is "404 Not Found at PerlSOAPExample.pl line 17 which turns out to be "my $response = $soap->GetWorkOrderList(SOAP::Data->new(name=>'siteId', value=>'BKK'));" so it seems like the data is just not going through and being received in Perl. When I entered the URL in Chrome or IE (http://MYSERVER-NAME:8732/Company.Department.Project.ProjectService.ProjectService/?wsdl) I do get the XML page returned by the Server. What am I doing incorrectly for Perl not to be able to consume the WCF Service? Any ideas? Anyone who has successfully accomplished communication between WCF and Perl?
