XElement and GetListItems

I use vS 2012 and .NET 4.0. I use Unit test.

I add Service Reference http://serverxxx:1090/desarrollo/aplicaciones/_vti_bin/lists.asmx

In app.config generate using http://serverxxx:1090/_vti_bin/lists.asmx

Unit Test method:

var client = new ListsSoapClient();

            client.ClientCredentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;
            client.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;

            var config = ConfigurationManager.OpenExeConfiguration("ProcDescQA.exe");
            var configPath = config.FilePath;
            Assert.IsTrue(File.Exists(configPath));

            var QueryList = config.AppSettings.Settings["QueryList"].Value;
            var ViewFields = config.AppSettings.Settings["ViewFields"].Value;
            var QueryOptions = config.AppSettings.Settings["QueryOptions"].Value;

            var Listamoss = config.AppSettings.Settings["Listamoss"].Value;
            var VistaMoss = config.AppSettings.Settings["VistaMoss"].Value;
            var PaginacionList = config.AppSettings.Settings["PaginacionList"].Value;

            var xmlDoc = new System.Xml.XmlDocument();
            var ndQuery2 = xmlDoc.CreateElement("Query");
            if (!String.IsNullOrEmpty(QueryList))
            {
                ndQuery2.InnerXml = QueryList;
            }
            var ndViewFields2 = xmlDoc.CreateElement("ViewFields");
            if (!String.IsNullOrEmpty(ViewFields))
            {
                ndViewFields2.InnerXml = ViewFields;
            }
            var ndQueryOptions2 = xmlDoc.CreateElement("QueryOptions");
            if (!String.IsNullOrEmpty(QueryOptions))
            {
                ndQueryOptions2.InnerXml = QueryOptions;
            }

            XElement ndQuery = XElement.Parse(ndQuery2.OuterXml);
            XElement ndViewFields = XElement.Parse(ndViewFields2.OuterXml);
            XElement ndQueryOptions = XElement.Parse(ndQueryOptions2.OuterXml);

            try
            {
                var data = client.GetListItems(Listamoss, VistaMoss, ndQuery, ndViewFields, PaginacionList, ndQueryOptions, null);

            }
            catch (FaultException ex)
            {
                Assert.Fail(ex.Message);
            }

For me, the signature for GetListItems method is

  public System.Xml.Linq.XElement GetListItems(string listName, string viewName, System.Xml.Linq.XElement query, System.Xml.Linq.XElement viewFields, string rowLimit, System.Xml.Linq.XElement queryOptions, string webID)

It uses XElement, not XmlElement neither XmlNOde.

And I get the same error Microsoft.SharePoint.SoapServer.SoapServerException about it.

Any suggestions?
