How to deserialize string with json.net - are there two versions of the library?

I want to deserialize a string (json) to an object (i'd like dynamic).

I use monodevelop and nuget packages

I have been looking for Json.net but also found Newtonsoft.Json.

And I could make a JArray by using Newtonsoft.Json.Linq.

I read on

Json.NET vs Newtonsoft.Json SerializationBinder is different

that these are two versions of the same library?

The main goal is to convert Json to Yaml.
