        query.ColumnSet = new Microsoft.Xrm.Sdk.Query.ColumnSet(true);
       // query.Criteria = filter;

        EntityCollection ec = organizationProxy.RetrieveMultiple(query);

        string fetchXml = @"<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>
            <entity name='account'>
            <attribute name='name'/>
            <attribute name='telephone1'/>
            </entity></fetch>";

        string ret = service.Fetch(fetchXml);
        res.XmlContent = ret;

        }


    catch (Exception ex)
    {
    }
    return res;
}

Any one have an idea of what is? Thanks a million

Don't know if there is something else, but you're missing your closing </Entity> Tag in your fetch XML.

Edit

wondering why you're rolling you're own Fetch SOAP.

Should just be doing something like this:

string fetchXml = @"<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>
    <entity name='account'>
    <attribute name='name'/>
    <attribute name='telephone1'/>
</fetch>";

EntityCollection ec = organizationProxy.RetrieveMultiple(new FetchExpression(fetchXml));

Also, OrganizationServiceProxy implements IDisposible and therefor should be wrapped in a using statement
