F# interactive throws NotImplementedException in PCLStorage

Question

I'm getting NotImplementedException trying to use PCLStorage.FileSystem.Current in F# interactive.

I downloaded PCLStorage with NuGet, right clicked on the reference and clicked "Send to F# interactive"

I'm working with VS2015 update 1, and I've re-installed the package as suggested in this answer

How can I get PCLStorage to work in F# interactive?

Answer 1

The PCL you've referenced is the one designed to target all platforms (Xamarin, Windows desktop, Windows phone etc). This dll is simply used as a means of defining all of the individual methods as part of the bait and switch PCL technique http://log.paulbetts.org/the-bait-and-switch-pcl-trick/ If you want to use the library with FSI then you'll need to add a specific reference to the appropriate platform's DLL. In this case you'll want to refer to the windows desktop version of the project which you downloaded from NuGet.
