Windows Phone 8应用失败，出现FileLoadException

Question

I am working on a Xamarin app, which works perfect on Android and iOS, but when I am running it on Windows Phone 8.1 (real device, haven't tried emulator). It fails with

Exception thrown: 'System.IO.FileNotFoundException' in mscorlib.ni.dll

It successfully gets to the 1st page (login-page), and I investigated on the server, that it gets called with success and a token is send in response.

program.Xamarin.DLL is an extension library I build, as it can be used in other projects.

If you are using a secondary solution, be sure they both are using the same NuGET package versions. This solved my problem
