I get following message when I try to add “Periodic Task” to “ScheduledActionService” in Windows Phone 8 Application.
“The drive cannot locate a specific area or track on the disk.”
I am really not sure if this is related to Visual Studio 2012 that I am using or related to Periodic Tasks on Windows Phone 8.
The same piece of code works fine in Windows Phone 7.
I found the solution here: http://social.msdn.microsoft.com/forums/en-us/wpdevelop/thread/a973955e-0981-4be8-8ac0-8dfcb9dc2917/
You need to manually update your WPAppManifest.xml file and configure the background task there.
Appears to be normal behavior, not related to emulator or debugging.
