.NET VB webservice - sending soap response

Question

I am attempting to send a soap response from a web service I have created. At the moment the response I'm sending is standard XML. How can I change this to respond in soap in this format: -

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:uiew="http://HSteindotnet.restrac.com/UIEWebServices/"&gt;
   <soapenv:Header/>
   <soapenv:Body>
      <uiew:AddRecordResponse><uiew:AddRecordResult>Success</uiew:AddRecordResult></uiew:AddRecordResponse>
   </soapenv:Body>
</soapenv:Envelope>
