Aspose.Words defines four publicly creatable COM objects i.e.
ComHelper, Document, DocumentBuilder and License. To access other
classes/methods available in Aspose.Words API, you must have to create
wrapper/helper classes. However, we will consider making all public API
accessible from COM and scripting languages in future. Your request has
been linked to the appropriate issue (WORDSNET-4977) in our issue tracking system and you will be notified as soon as it is resolved. Sorry for the inconvenience.
