Since pulling the latest version of our cross-platform code I'm unable to build the iOS code in Xamarin Studio. The nuget package restore stage gets the following error:
The schema version of 'Newtonsoft.Json' is incompatible with version 2.2.31210.9045 of NuGet. Please upgrade NuGet to the latest version from http://go.microsoft.com/fwlink/?LinkId=213942
The package is referenced in a PCL project and has presumably been updated on Windows.
I've tried deleting the Mac's nuget cache at '~/.local/share/NuGet/Cache' but that didn't help.
How do I upgrade nuget in mono/OS X?
Xamarin Studio Version 6.0.2 (build 73)
Xamarin.iOS Version: 18.104.22.168 (Xamarin Studio Community)
