ASP.NET provides an extensibility mechanism for calling Web Services using SOAP. The extensibility mechanism revolves around a SoapExtension that can inspect or modify a message at specific stages in message processing on either the client or the server. This enumeration specifies the processing stage of the SoapMessage.

The following code example is a fragment of a SOAP extension, which implements the ProcessMessage method. Within the ProcessMessage method, processing of a SoapMessage is handled specific to the SoapMessageStage.

  ' Process the SOAP message received and write to log file.
  Public Overrides Sub ProcessMessage(message As SoapMessage)
     Select Case message.Stage
        Case SoapMessageStage.BeforeSerialize
        Case SoapMessageStage.AfterSerialize
        Case SoapMessageStage.BeforeDeserialize
        Case SoapMessageStage.AfterDeserialize
        Case Else
              Throw New Exception("invalid stage")
     End Select
End Sub 'ProcessMessage
