问题
I am currently developing a stopwatch and timer app in C#/XAML for Windows Phone 8. While using my app on my phone, I found that it randomly closed out/crashed and that too at different points of use (i.e. I wasn't doing the same thing each time it closed out). While debugging, I found that my app closed out with the following error code in my output window:
"The program '[1100] TaskHost.exe' has exited with code -2147220717 (0x80040313)."
I am very confused as to why this is happening. I tried creating an entirely new solution and moving my code over and I've still been getting the same issue. I have tried using the app on multiple different devices, and the same thing happens (even in the Emulator). Sometimes the app crashes after 5 minutes of use, sometimes it crashes after 30 minutes of use, it's very unpredictable which makes it very hard to find the root of the problem. My app uses the XNA Framework to play an audio sound and the Coding4Fun Toolkit for a TimeSpanPicker control, and besides that there isn't much else that's particularly notable about my app. I have tried removing the playing of the audio file and removing references to the XNA Framework, and the problem persists.
Any ideas on what the problem could be?
Thanks in advance!

That what David said + are you sure that the phone is not running out of memory?
Edit try a windows phone analysis(Alt +F1 | Debug->Start windows phone application analysis)

If you're using XNA framework in WP project you can get a crash when updating the UI thread. You might need to run it through a Dispatcher?
Dispatcher.BeginInvoke(() => {
// Call your update UI methods here..
});
