Public Property PowerMode As RadioPowerMode
public RadioPowerMode PowerMode { get; set; }

Property Value

Type: Microsoft.Devices.Radio..::.RadioPowerMode
Returns RadioPowerMode.


When your application is deactivated, such as when receiving a Deactivated event, the radio will not stop playing automatically. As a best practice, set PowerMode to 'off' when your application is deactivated, to prevent background playback.


FM radio is supported only in apps that target Windows Phone OS 7.1. If you use the FMRadio class in apps that target Windows Phone OS 8.0 or later, a RadioDisabledException indicates that the FM radio feature is not available. On Windows Phone 8 devices with a build of 8.0.10322 or greater, the run-time exception may not occur if you use the FMRadio API. However, the FMRadio API is not supported for apps that target Windows Phone OS 8.0.
