Adding Json.Net to a Unity3D project
I had just the same problem in Visual Studio 2015. But Utamaru's solution worked for me.
Make a folder: Assets/Plugins where you put the *.dll file and add it as a reference.
To add a reference you highlight the Analyzers in the Solution Explorer in Visual Studio and under Project > Add Reference you can find your *.dll file located in Assets/Plugin by browsing to it.
For support in built versions, recommended to use one of following
Json.NET v12.0github.com/jilleJr/Newtonsoft.Json-for-UnityJson.NET v9.0github.com/SaladLab/Json.Net.Unity3DJson.NET v8.0parentelement.com/assets/json_net_unityJson.NET v7.0nuget.org/packages/Unity.Newtonsoft.Json/
Or if you dont require Newtonsoft.Json (Json.NET), here's some other alternatives (all works in Unity, I've omitted libraries that don't, and there's a lot of 'em):

There is quite the table of candy to select from. Choose well young padawan~
Use simpleJson. Its free and gets the work done.
Copy the SimpleJSON.cs contents into a newly created file in your project and you're ready to go. If you want to be fancy -> create this new file in assets\plugins directory
