BackgroundUploader.getCurrentUploadsAsync() is returning most of the transfers I've ever done

Question

I'm working on a Metro app that will upload and download some files. MS provides a couple examples: http://code.msdn.microsoft.com/windowsapps/Background-Transfer-Upload-457ae763 http://code.msdn.microsoft.com/windowsapps/Background-Transfer-Sample-d7833f61

The first one is an uploader app, and the 2nd is a downloader app. As Win8 can suspend and kill an app when it goes out of focus, the downloader app provides for retrieving the active downloads so I can start receiving updates about the status. The Uploader app does not. I have tried to add this functionality, but getCurrentUploadsAsync() is returning 18 transfers that I have already completed. I have tried everything I can think of to remove these transfers, but it does not change the results of getCurrentUploadsAsync().

Does anyone know how to clear out "dead" BackgroundTransfers in WinRT?

Answer 1

You have to call the cancel method like explained there : http://www.jonathanantoine.com/2013/02/05/winrt-how-to-cancel-a-background-download-operation/

theDownloadOperation.AttachAsync().Cancel();
