How to load Entity Framework related objects

Question

I study Entity Framework Core and start by using the first code approach when reading this guide https://docs.efproject.net/en/latest/platforms/aspnetcore/new-db.html , with the exception of different models.

In EF6, it had lazy loading, and I was able to easily pull related objects, but in EF Core it does not work. I was wondering how to do this, or if there is work to make it work.

Here is an example of how my two models look:

public class Team
{
    public string Id { get; set; }
    public string Name { get; set; }
    public string Icon { get; set; }
    public string Mascot { get; set; }
    public string Conference { get; set; }
    public int NationalRank { get; set; }

    public List<Game> Games { get; set; }
}

public class Game
{
    public string Id { get; set; }
    public string Opponent { get; set; }
    public string OpponentLogo { get; set; }
    public string GameDate { get; set; }
    public string GameTime { get; set; }
    public string TvNetwork { get; set; }
    public string TeamId { get; set; }

    public Team Team { get; set; }
}

I want to get all the games for the team, but at the moment this is zero.

Web Api, TeamsController, GET , Games, .

:

[HttpGet]
public async Task<List<Team>> Get()
{
    return await _context.Teams.Include(t => t.Games).ToListAsync();
}

JSON:

[
  {
    "id": "007b4f09-d4da-4040-be3a-8e45fc0a572b",
    "name": "New Mexico",
    "icon": "lobos.jpg",
    "mascot": "New Mexico Lobos",
    "conference": "MW - Mountain",
    "nationalRank": null,
    "games": [
      {
        "id": "1198e6b1-e8ab-48ab-a63f-e86421126361",
        "opponent": "vs Air Force*",
        "opponentLogo": "falcons.jpg",
        "gameDate": "Sat, Oct 15",
        "gameTime": "TBD ",
        "tvNetwork": null,
        "teamId": "007b4f09-d4da-4040-be3a-8e45fc0a572b"
      }
    ]
  }
]

:

[HttpGet]
public async Task<List<Team>> Get()
{
    return await _context.Teams.ToListAsync();
}

, Games null.
