WCF adds string to xml

WCF

Hi guys,

I have a problem that I seem unable to solve. Since I cannot find anything on it on the web I assume it's either incredibly stupid, or rather unique.

I have a WCF service that works well. It creates an XMLDocument and return doc.InnerXML. I debbuged its contents, this is 100% correct XML.

But.

If I call the service from a browser (or directly call the service from code) I get something extra that I did not expect, or can get rid off:

<?xml version="1.0" encoding="UTF-8"?>
<string><tblPatientCollection><tblPatient FirstName="E.M.J."><PatientId>7</PatientId><decimal>1,2</decimal></tblPatient></tblPatientCollection></string>

Notice the

<string>

at the beginning and the closing string at the end? The doc itself does not contain that, as I can see when I debug the code.

Could it be my config? Something else?

<system.serviceModel>
   <services>
     <service behaviorConfiguration="ServiceBehavior" name="iOSService.TheService">
       <endpoint address="" behaviorConfiguration="web" binding="webHttpBinding" contract="iOSService.TheImplementation" />
     </service>
   </services>
   <behaviors>
     <serviceBehaviors>
       <behavior name="ServiceBehavior">
         <serviceMetadata httpGetEnabled="True" />
         <serviceDebug includeExceptionDetailInFaults="True"/>
       </behavior>
     </serviceBehaviors>
     <endpointBehaviors>
       <behavior name="web">
         <webHttp defaultOutgoingResponseFormat="Xml" defaultBodyStyle="Bare" helpEnabled="False" />
       </behavior>
     </endpointBehaviors>
   </behaviors>
   <serviceHostingEnvironment multipleSiteBindingsEnabled="True" />
 </system.serviceModel>

Help would be very much appreciated!

Thx, Michel.
