Your background process cant directly interact with other apps or directly with the UI. The only way you can interact with the user in some way is for example to change the App tile or issue a Toast Notification. If you let us know what you are trying to accomplish it may be easier to help

Sir ,I'm getting xml(that contains list of questions with their time attribute) from my web service. In OnInvoke method I'm calling the service.Service is called at every 11:00 am.After getting the list of questions in the returned xml i Need to show them on the UI(that has 2 or more controls in it).Questions will be shown at their specified times.Directly UI should be called 'No Toast ,Tile etc should be clicked' .If it's posible then how
Pls suggest- Provide some solutions.
thanks.

An interesting detail is that the list of unsupported API-s (http://msdn.microsoft.com/en-us/libr...(v=vs.92).aspx) does not explicitly disable UI creation attempts.
However

Directly UI should be called 'No Toast ,Tile etc should be clicked'

is not possible on Windows Phone. If the application is switched to the background or not running at all, the background agent will not be able to bring it to the foreground.

The only way to achieve it is through
Steps:
1. If(UseToastNotification)
{
2. If(UserSelectToast)
{
//Your UI will be invoked.
3. //Do you logic.
}
4. else
{
//Show Notification count (Message) on your application Tile
}
}
else
{
//Can't achieve it. Like other user mentioned in this thread
}
Thanks and Regards
