Where is the RestRequest class?

Question

In the C# tab of the getting started of maingun API, I find the following code.

public static RestResponse SendSimpleMessage() {
       RestClient client = new RestClient();
       client.BaseUrl = "https://api.mailgun.net/v2";
       client.Authenticator =
               new HttpBasicAuthenticator("api",
                                          "key-3ax6xnjp29jd6fds4gc373sgvjxteol0");
       RestRequest request = new RestRequest();
       request.AddParameter("domain",
                            "samples.mailgun.org", ParameterType.UrlSegment);
       request.Resource = "{domain}/messages";
       request.AddParameter("from", "Excited User <[email protected]>");
       request.AddParameter("to", "[email protected]");
       request.AddParameter("to", "[email protected]");
       request.AddParameter("subject", "Hello");
       request.AddParameter("text", "Testing some Mailgun awesomness!");
       request.Method = Method.POST;
       return client.Execute(request);
}

When I google the name of the class, I find several reference to this class in different contexts. However, I can't seem to find the fully qualified name of the RestRequest class anywhere on the mailgun website, google or MSDN to find it's documentation.

Anybody can point out where is this class defined ?

The code looks like it uses RestSharp.
