How to prevent MediaCapture.CapturePhotoToStreamAsyn() from hanging?

Question

There is an old thread related to this. MediaCapture.CapturePhotoToStreamAsyn() hangs immediately when an app is brought to the background.  This true at least on a Surface RT. I have two questions:

1. Is there anything of MediaCapture that can be tested to determine whether calling CapturePhotoToStreamAsyn() will hang?
2. Is there a way to make CapturePhotoToStreamAsyn() generate an exception instead of hanging?

Hello Hong,

Can you please reproduce the hang, wait about 15 seconds and then capture a mini-dump with full memory and heap information in it. Can you then please zip (not rar) it up and put it on your SkyDrive. Then please post a link to the file on SkyDrive here. I will download the file and do what I can to diagnose the problem.

Thanks,

James

Hello James,

Thanks a lot for looking into this.  Here is the zipped dump file.

Though this issue is manageable, it is a major nuisance for the app.
