I have a serious problem when I launch my app on an iPhone 6s. It crash after the splash screen without entering in debug (doesn't stop in main function nor in AppDelegate). I try to unload some class and then it works. So I try to investigate more and i found that if i change some class name it works without unload that class.. but for other I need to comment some methods or it start to crash at startup again.
I use VS with Xamarin extension (version 4.0.3)
