Windows phone 8.1 application failed in release when I use background tasks

I added a background task to my Windows Phone 8.1 app. And it works as expected, but only in Debug mode. I always get the RootFrame_NavigationFailed exception when I run my application in Release mode.

How can I debug it in Release to know the reason of the RootFrame_NavigationFailed?

The app doesn't have any information in exception in Release mode.

What kind of background tasks are you using? Where/when exactly do you get the error? – Romasz
Windows Runtime Component (.winmd). When I run my app. – Mark Twain
How your BTask is triggered (TimeTrigger, Maintance)? Or it's BackgroundAudio task? How it's connected with your App? Have you tried to debug Suspending event? – Romasz
It's the timer background task which I referenced to my app. I can't use debug events, because I've got exception instantly after my app run. – Mark Twain
But you have said that it works in Debug mode. If you remove BTask from the code - does the app work fine? Are you able to say what lines cause the problem? Or maybe you are able to share a project with the problem? – Romasz

So, after 2 weeks of trying to resolve this issue I moved my application to Windows Phone 8.1 runtime from Silverlight.

It costs me 3 evenings and my problem was disappeared. I'm very unhappy that this is the solution, but I can't figure out, what is really wrong. Because my library works great with background tasks in Windows Phone 8.1 runtime.
