Hello, I've got a client application (in Flex 3) which calls a very heavy function in a .net Webservice., Because the operation can take a while to complete, I'd like the webservice to update a progressbar in the client application.
Obviously it's not that easy, since it's an asynchronous call and the client application only listens for the completion of the request. How can I achieve that ? Do I need to use a different technologies (WCF maybe ?) Thanks
