Parameters

extension: IMediaExtension

An object that implements IMediaExtension.

connection: AppServiceConnection

An AppServiceConnection object that represents an endpoint connection for an app service.

Windows requirements

Device family	Windows 10 Creators Update (introduced in 10.0.15063.0)
API contract	Windows.Foundation.UniversalApiContract (introduced in v4.0)

Remarks

Call this method from within the Run method of a Windows Runtime Component that exposes your media extension.

Get an instance of AppServiceConnection by casting the TriggerDetails property of the IBackgroundTaskInstance passed into the Run method to an AppServiceTriggerDetails object and then accessing the AppServiceConnection property.

In order for your background task to receive an AppServiceTriggerDetails object, you must register it as an app service in you app manifest file. For more information, see Create and consume an app service.
