Windows Store 8.1 sending UnhandledExceptionEventArgs not supported

Application is Windows 8.1 Universal Application (code is for Windows)

private void OnUnhandledException(object sender, UnhandledExceptionEventArgs e) {
    this.raygunClient.Send(e);
}

I'm getting:

sparkiy-client\SparkiyClient\SparkiyClient\SparkiyClient.Shared\App.xaml.cs(98,27,98,28):
error CS1503: Argument 1: cannot convert from 'Windows.UI.Xaml.UnhandledExceptionEventArgs' to 'System.Exception'

Ok, I just found in documentation that I can use .Attach instead of manually calling Send.

** EDIT:

Me, the idiot, blindly following instructions without actually understanding what lines do, I just needed to add .Exception to the args param and send that.

It seems that my application isn't reporting exceptions. I have tried placing exception on many places, debugging app in Debug/Release, start w/o debugging - still nothing appears on App overview.

Here is my code: https://github.com/Sparkiy/sparkiy-client/blob/edge/SparkiyClient/SparkiyClient/SparkiyClient.Shared/App.xaml.cs

I have tested that too. It does get hit and there is no error. Here is Debug output: http://pastebin.com/UGDtZLY6

Ok, It was my fault. I disabled Internet access in package manifest so that I don't have to write privacy policy for windows store certification. Well I guess I'll have to write one now :D

Everything is working properly. Thanks!
