Windows Phone 8.1: Scan Barcodes using Camera

问题

I want to scan/read barcodes using camera in Windows Phone 8.1 by BarcodeScanner class of the SDK:

http://msdn.microsoft.com/en-us/library/windows/apps/windows.devices.pointofservice.barcodescanner.aspx

Is there any example available? How can I use this?

Edit: It seems PointOfService namespace is for Windows but Windows Phone. Is there any similar library available?
