Compiler error when calling ValidateWorkflowMarkupAndCreateSupportObjects

Hi,

I created a workflow in sharepoint designer then i exported xoml, xoml.rules, xoml.wfconfig.xml files from it.

I want to deploy these files in sharepoint using a host application (Windows Forms application). So, I call ValidateWorkflowMarkupAndCreateSupportObjects and AssociateWorkflowMarkup method from the WebPartPagesWebService class.

This is the code:

            string XomlFile = @"D:\wkf\rami workflow designer.xoml";
            string RulesFile = @"D:\wkf\rami workflow designer.xoml.rules";
            string ConfigFile = @"D:\wkf\rami workflow designer.xoml.wfconfig.xml";
            string flag = "2";

            websvcWebPartPages.WebPartPagesWebService service = new websvcWebPartPages.WebPartPagesWebService();
            service.UseDefaultCredentials = true;
            service.PreAuthenticate = true;
            string result = service.ValidateWorkflowMarkupAndCreateSupportObjects(XomlFile, RulesFile, ConfigFile, flag);
            service.AssociateWorkflowMarkup(ConfigFile, "V1.0");

ValidateWorkflowMarkupAndCreateSupportObjects return "Data at the root level is invalid. Line 1, position 1".

And AssociateWorkflowMarkup throw Microsoft.SharePoint.SoapServer.SoapServerException.

The Logs file:

When i deploy the workflow using Sharepoint Designer it works. But i want to deploy it with a customized application in a first step then create my own workflow designer in second step.
