Protected Overridable Sub OnRun (taskInstance As IBackgroundTaskInstance)

Parameters

taskInstance: IBackgroundTaskInstance

An interface to an instance of the background task. The system creates this instance when the task has been triggered to run.

Remarks

Important

To keep the memory footprint of the background task as low as possible, this task should be implemented in a C++ Windows Runtime Component for Windows Phone. The memory footprint will be higher if written in C# and will cause out of memory exceptions on low-memory devices which will terminate the background task. For more information on memory constraints, see Support your app with background tasks.
