 # Newtonsoft Json.NET for Unity3D
+
+[Newtonsoft Json.NET](http://www.newtonsoft.com/json) is a de facto standard JSON library in .NET ecosystem.
+But it doesn't support Unity3D, so it's a little bit hard to use JSON.NET just after getting [Json.NET package](https://www.nuget.org/packages/Newtonsoft.Json/).
+This package is for Unity3D programmers that need to use latest Json.NET in Unity3D.
+
+## Where can I get it?
+
+Visit [Release](https://github.com/SaladbowlCreative/Json.Net.Unity3D/releases)
+page to get latest Json.NET unity-package.
+
+## What's the deal?
+
+Unity3D has old-fashioned and bizarre .NET Framework like these :)
+ - Basically based on .NET Framework 3.5 ([forked Mono 2.6](https://github.com/Unity-Technologies/mono/commits/unity-staging))
+ - Runtime lacks some types in .NET Framework 3.5 (like System.ComponentModel.AddingNewEventHandler)
+ - For iOS, dynamic code emission is forbidden by Apple AppStore.
+
+Because Newtonsoft Json.NET doesn't handle these limitations, errors will welcome you
+when you use official Json.NET dll targetting .NET 3.5 Framework.
+
+## What's done?
+
+Following works are done to make Json.NET support Unity3D.
+
+ - Based on Newtonsoft Json.NET 7.0.1.
+ - Disable IL generation to work well under AOT environment like iOS.
+ - Remove code related with System.ComponentModel.
+ - Remove System.Data and EntityKey support.
+ - Remove XML support.
+ - Remove JPath class to reduce size of DLL.
+ - Remove DiagnosticsTraceWriter support.
