Thank you for writing.
Please confirm that you have followed the whole instructions. That is initialize the ApplicationUsageHelper
and call it's OnApplicationActivated
sender, LaunchingEventArgs e)
sender, ActivatedEventArgs e)
If after that you still get an exception, please send us a sample project that we can use to reproduce the exception or let us know of the exact steps we need to perform in order to reproduce it in a blank application.
I hope this information helps.
