RestSharp deserialize JSON to dynamic

DynamicJsonDeserializer.cs

// ReSharper disable CheckNamespace
namespace RestSharp.Deserializers
// ReSharper restore CheckNamespace
{
    public class DynamicJsonDeserializer : IDeserializer
    {
        public string RootElement { get; set; }
        public string Namespace { get; set; }
        public string DateFormat { get; set; }

        public T Deserialize<T>(RestResponse response) where T : new()
        {
            return JsonConvert.DeserializeObject<dynamic>(response.Content);
        }
    }
}

ExampleUsage.cs

// Override default RestSharp JSON deserializer
client = new RestClient();
client.AddHandler("application/json", new DynamicJsonDeserializer());

var response = client.Execute<dynamic>(new RestRequest("http://dummy/users/42"));

// Data returned as dynamic object!
dynamic user = response.Data.User;

// Remember properties are actually Json.NET JObjects so you have to call .Value to retrieve their string contents.
string firstName = user.FirstName.Value;
string lastName = user.LastName.Value;

To get this to work with 104.1, I had to change line 5 of DynamicJsonDeserializer.cs to use the interface (IRestResponse response) instead of the concrete class (RestResponse response). Also, I had to remove the generic constraint about where T : new() for the same reason.

I've posted a blog post with a full(er) write-up here: http://www.csharpcity.com/2013/deserializing-to-dynamic-with-restsharp/ that links to this gist.
