The Windows Phone 8.1 project runs successfully only on an emulator;
when deployed to a device it raises an exception at the
Forms.Init related to its inability to load the FSharp.Core.dll library.
This problem cannot be fixed by adding a reference to FSharp.Core.dll,
either through referencing the file in the Reference Assembles directory, or by installing the FSharp.Core NuGet package.
