There are two entities Task and User. Task entity has two foreign keys (both int - id) Performer and Creator that is linked to User entity Id field. They are shadow properties, so in db their name are PerformerId and CreatorId. When I try to test POST request, Swagger shows Json structure like this and requires Creator not CreatorId:

{
  "id": 0,
  "name": "string",
  "description": "string",
  "status": 0,
  "creator": {
    "id": 0,
    "fullName": "string",
    "roleId": 0,
    "email": "user@example.com",
    "password": "string"
  },
  "performer": {
    "id": 0,
    "fullName": "string",
    "roleId": 0,
    "email": "user@example.com",
    "password": "string"
  }
}

The question is how to make program to get Json structure like this one, only IDs of foreig keys, not the every field:

{
      "name": "string",
      "description": "string",
      "status": 0,
      "creatorId": int,
      "performerId": int: 
}

That is how my Task model looks like:

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

        public string Name { get; set; } = String.Empty;
        
        public string? Description { get; set; }

        public Statuses Status { get; set; }

        public User Creator { get; set; }

        public User? Performer { get; set; }
    }
    public enum Statuses
    {
        NotStarted,
        Completed
    }
}

And there is my POST request from controller:

[HttpPost]
public IActionResult CreateTask([FromBody] Data.Entities.Task task)
{
  if (task == null)
  {
     return BadRequest();
  }
            
  _context.Tasks.Add(task);
  _context.SaveChanges();

  return CreatedAtRoute("GetTaskById", new { id = task.Id }, task);
}

What I have tried:

Tried to configure in model itself.
