WrongThreadException when debugging app

[briangabriel]

When starting the app via the debugger in VS2017 it exits almost immediately with the following unhandled exception:

Exception thrown at 0x76FF07F2 (KernelBase.dll) in vfl-ipad-01.exe: WinRT originate error - 0x8001010E : 'The Application Object must initially be accessed from the multi-thread apartment.'.

It might be that you trying to sent notification to NSNotificationCenter from another thread than main. Really hard to say without the code or any clues about actual place where you caught the exception.
