Assembly: Microsoft.Phone (in Microsoft.Phone.dll)
Use this method during application development to test your background agent implementation. Background agents are launched by the operating system according to the type of agent and the current state of the system. This scheduling logic is described in Background agents for Windows Phone 8. You can use this method to launch an agent more frequently from your foreground application or from the agent itself in order to test the agent execution. This method should only be used during development. You should remove calls to this method from your production application.
You should set the delay value to at least 60 seconds to ensure that the background agent will be launched. Delay times less than 60 seconds may result in the background agent not being launched.
