Automatic id generation and mapping _id NEST

Id not populated

using System;
using System.Linq;
using NUnit.Framework;

namespace Nest.AutoId
{
    [ElasticType(Name = "data", IdProperty = "Id")]
    public class DataForGet : DataForIndex
    {
        public string Id { get; set; }
    }

    [ElasticType(Name = "data")]
    public class DataForIndex
    {
        public string Name { get; set; }
        // some other fields...
    }

    [TestFixture]
    public class ElasticsearchTests
    {
        readonly ElasticClient client = new ElasticClient(new ConnectionSettings(new Uri("http://localhost:9200")));
        [Test]
        public void index_an_item()
        {
            var data = new DataForIndex
                {
                    Name = "Dave"
                };

            client.Index(data, "index");
        }

        [Test]
        public void get_an_item()
        {
            var item = client.Search<DataForGet>(x => x.Index("index"));

            Console.WriteLine(string.Join(Environment.NewLine, item.Documents.Select(x => x.Id + " : " + x.Name)));

        }
    }
}

Posible workaround:

var item = client.Search< DataForGet >(x => x.Index("index").MatchAll());
var list = item.DocumentsWithMetaData.Select(x => { x.Source.Id = x.Id; return x.Source; }).ToList();

@TinTin04 you are correct here.

When working with autoassigned id's you will have to use the full IHit<T> object in DocumentsWithMetaData.

this is not testable in it's entirety given .Select is an extension method (i'm constrained to using just Moq). Is there an alternative? possibly with the mappings itself?
