Using Newtonsoft.Json in a Visual Studio extension
The ever popular Newtonsoft.Json NuGet package by James Newton-King is used throughout Visual Studio’s code base. Visual Studio 2015 (14.0) was the first version to ship with it. Later updates to Visual Studio also updated its Newtonsoft.Json version when an internal feature needed it. Today it is an integral part of Visual Studio and you can consider it a part of the SDK alongside other Visual Studio assemblies.
