when i read about Windows 8 store app i found that on MSDN :
Supporting your app with background tasks
CPU usage is limited as follows:
If App not on lock screen : CPU usage quota ( 1 second) &
Refresh time (2 hours )
If App on the lock screen: CPU usage quota ( 2 hours ) &
Refresh time (15 minutes)
does that mean that i can't run background task every (10 ) miuntes ? only i will restricted with minimum (15) minutes ?
