>Could you elaborate a bit more ... I have no idea what you mean by high level and low level.

When a Web Service is define and when it contains a method such as:

   <WebMethod()> _
   Public Function GetProfileDataSet(ByVal tnMember As Integer) As DataSet
      Dim lcXML AS String
      lcXML="..."
      Return lcXML
   End Function

it is high level as we don't have to serialize everything and just deal with the XML itself that has to be returned. But, for a specific method, I have to serialize everything such as creating the entire SOAP envelope. So, I'm wondering what would need to be done, as far as creating a new method, which would allow me to build the entire SOAP envelope?

Or, maybe .NET offers something much simpler that can be used at high level as well.
