title: Delay the application closing of windows phone
body: <p>Is it possible to delay the application closing event in windows phone. What i trying to achieve is, i need to send a web request(for sending the usage time of application) for achieving analytics in my application. So based on my current implementation before complete sending the request the main thread exits and application closes. What is the alternative to fix this issue. I cannot send the request in next application start(this fix i am not expecting)</p>
