I'm told by Trevor Hancock at Microsoft that the SOAP Toolkit doesn't support asynchronous web services. Options are to either build a stateful system and poll the server for completion, or to build the client in .NET.

A third option I thought of afterward might be to use .NET Web Service Studio (available at GotDotNet.com) to listen to the SOAP conversation during an asynchronous .NET web service call, and duplicate it in VFP using low-level SOAP calls.

During the course of the conversation I asked him why man exists; he replied that while version 1.0 of the appropriate Microsoft software program can't answer that question, the upcoming release of version 2.0 is expected to be able to do so.
