ASP.NET

Hey guys, I'm building an asp.net web api and I've been using this guide as a reference http://www.asp.net/web-api/overview/data/using-web-api-with-entity-framework/part-5[^]

What I want to do is when someone does a GET to this api they get all the info except the Id(which is auto-incremented). For this purpose I have this controller:

// GET: api/Events/5
        [ResponseType(typeof(EventDto))]
        public async Task<IHttpActionResult> GetEvent(int id)
        {
            var events = await db.Events.Include(e => e.Id).Select(e =>
                new EventDto()
                {
                    Name = e.Name,
                    Project = e.Project,
                    Objectives = e.Objectives,
                    City = e.City,
                    Country = e.Country,
                    EventStart = e.EventStart,
                    Departure = e.Departure,
                    Arrival = e.Arrival,
                    Registration = e.Registration,
                    NationalTransportation = e.NationalTransportation,
                    Accommodation = e.Accommodation,
                    AcNumberNights = e.AcNumberNights,
                    AcPreferHotel = e.AcPreferHotel,
                    AcPreferHotelUrl = e.AcPreferHotelUrl,
                    Flight = e.Flight,
                    FlDeparture = e.FlDeparture,
                    FlDepartPrefer = e.FlDepartPrefer,
                    FlDepartPreferUrl = e.FlDepartPreferUrl,
                    FlReturn = e.FlReturn,
                    FlRetPrefer = e.FlRetPrefer,
                    FlRetPreferUrl = e.FlRetPreferUrl,
                    Notes = e.Notes,
                    Files = e.Files,
                    Status = e.Status
                }).SingleOrDefaultAsync(e => e.Id == id);
            if (events == null)
            {
                return NotFound();
            }

            return Ok(events);
        }  

Which is using a DTO that from what I understood is how I control what is returned in the GET

and I have this DTO:

public class EventDto
    {
        public int Id { get; set; }

        public string Name { get; set; }

        public string Project { get; set; }

        public string Objectives { get; set; }

        public string City { get; set; }

        public string Country { get; set; }

        public DateTime EventStart { get; set; }

        public DateTime Departure { get; set; }

        public DateTime Arrival { get; set; }

        public string Registration { get; set; }

        public string NationalTransportation { get; set; }

        public string Accommodation { get; set; }

        public int AcNumberNights { get; set; }

        public string AcPreferHotel { get; set; }

        public string AcPreferHotelUrl { get; set; }

        public string Flight { get; set; }

        public DateTime FlDeparture { get; set; }

        public string FlDepartPrefer { get; set; }

        public string FlDepartPreferUrl { get; set; }

        public DateTime FlReturn { get; set; }

        public string FlRetPrefer { get; set; }

        public string FlRetPreferUrl { get; set; }

        public string Notes { get; set; }

        public string Files { get; set; }

        public string Status { get; set; }
    }

What is happenning is that I'm using postman (chrome extension to test api) and I use a GET api/Events/1 and it returns:

[
    {
        "Id": 0,
        "Name": "psilva",
        "Project": "a",
        "Objectives": "s",
        "City": "a",
        "Country": "s",
        "EventStart": "2015-02-06T11:06:23.673",
        "Departure": "2015-02-06T11:06:23.673",
        "Arrival": "2015-02-06T11:06:23.673",
        "Registration": "a",
        "NationalTransportation": "a",
        "Accommodation": "a",
        "AcNumberNights": 1,
        "AcPreferHotel": "a",
        "AcPreferHotelUrl": "a",
        "Flight": "a",
        "FlDeparture": "2015-02-06T11:06:23.673",
        "FlDepartPrefer": "a",
        "FlDepartPreferUrl": "a",
        "FlReturn": "2015-02-06T11:06:23.673",
        "FlRetPrefer": "a",
        "FlRetPreferUrl": "a",
        "Notes": "a",
        "Files": "a",
        "Status": "a"
    }
]

Why is return "Id" ? and why is it "0"?
