I am using the latest SDK for Windows Phone 8.1. I just recently updated all my other SDKs to the latest and used NuGet to get the JSON package. The editor is having an error with the library versions.
When I use an JSON.Net classes, it gives me an error in the editor (not compile or run time) saying I'm using the wrong version of XML.Linq. It keeps saying I need 18.104.22.168.
