Let me ask few questions to clarify myself.
- Are you trying to consume a WSDL, which is created in ByD, in ByD?
- Why do you want to consume the WSDL in silverlight
?
Anyways, if you are looking to consume a ByD webservice in ByD again, then you can create an "External web service Integration" in PDI and call that in ABSL. If the web service doesnt need authentication, then you can create a Mashup Web service.
