I’m having a (hopefully) simple issue. I added the Newtonsoft Json (v1.1.2) package to my project, shown below:
But when I try to use it, there’s no assembly/library I can seem to reference (in my AssemblyDefinition, shown in the screenshot below).
Also, using Newtonsoft.Json; does not work in my C# code.
So how do I use this package? Am I doing something silly?
Figured it out myself 2 days ago ! You have to check the “Override References” on your amsdef, then there is a new list where you can put .dll 
Oh, that worked!!
'Wish they would have put a note about that in the docs for the package I suppose. For future reference, this is what my AssemblyDefinition (.asmdef file) looks like now:
and the using Newtonsoft.Json; statement works now! Thanks for the help
