How can I get data usage programmatically on my WP8? I found class DataUsage with properties BytesReceived and BytesSent. But on MSDN I found the following:
Remarks Windows Phone 8
This API is not implemented and will throw an exception if called.
Perhaps, somebody knows how can I get the traffic usage (for cellular/Wifi connection)?
Unfortunately, there’s no API to get the overall traffic usage of the phone. Or at least, none available to third-party developers (there’s probably some kind of internal API since Data Sense is able to display that information).
