Is there a sdk/lib to parse gdata (json) data returned by the Google Contact API v3?

Question

I'm currently accessing google contacts via GoogleContact API v3. I use the following command:

"https://www.google.com/m8/feeds/contacts/default/full?access_token=" + token.access_token + "&alt=json&v=3&q=Susan"

It returns me a json structure response in gdata format.

        }]
    }]
}

}

Currently, I have the response and create my own method to access each filed. Is there an already defined library that will convert this into a more readable object?

For example, "gd$name" I'm guessing is the google data representation of a name. Is there a way to convert it to a gData contact object that gives me the name field without me having to write my own gData parser?

Thanks Derek

The API reference can be found here: https://developers.google.com/google-apps/contacts/v3/

A .NET SDK (client library) can be found here: https://www.nuget.org/packages/Google.GData.Contacts/

Examples of how to use the client library can be found in the API reference.
