Location Tracking in Background

I am developing a windows phone app that uses users current location, I am making the app in 7 OS. My question is, Can I track the location in background, that is when the screen is locked? I know this is a possibility in wp8 as it provides us with GeoLocator class, but can I achieve this in wp7? I am basically making a runtracker app hence I would like my app to track the location even when its in background, is it really feasible? Your help is always appreciated!!

It is possible to keep the app running under lock screen, as it does, for example, Endomondo app.

Using Idle Detection, you can keep the app on, although screen is locked, and you can keep on tracking the location. Actually, it is not running in background, but in the foreground. Just the screen is locked. So, be careful not to drain user's battery.

You have to set the PhoneApplicationService.ApplicationIdleDetectionMode property to Disabled, for example in InitializePhoneApplication() method in App.xaml.cs:

PhoneApplicationService.Current.ApplicationIdleDetectionMode = IdleDetectionMode.Disabled;

Note that there are special certification requirements for this type of apps. Refer to section 6.3 (Apps running under a locked screen) of the following page:

Additional requirements for specific app types for Windows Phone

GeoCoordinateWatcher Class exists in WP7, but here is the documentation from MSDN -

This API, used for obtaining the geographic coordinates of the device, is supported for use in background agents, but it uses a cached location value instead of real-time data. The cached location value is updated by the device every 15 minutes.
