I have a service class and I have the User responsible for the service, which is a user of IdentityUser .

Remembering that I changed the String Identity Id to "Int", just that.

I can usually register, however, when I edit, it lists the users, but does not set the user who is already registered in the service.

Entity:

[Table("Atendimentos")]
public class Atendimento
{
    [Key]
    public int AtendimentoId { get; set; }
    public int UsuarioId { get; set; }

    [Display(Name = "Responsável pelo atendimento")]
    public virtual Usuario Usuario { get; set; }
}

Controller:

ViewBag.UsuarioId = new SelectList(db.Users.Select(x => new { UsuarioId = x.Id, Nome = x.Nome + " " + x.Sobrenome }), "UsuarioId", "Nome");

View:

@Html.DropDownList("UsuarioId", null, htmlAttributes: new { @class = "form-control" })

I have tried to put the property "UserId" to "Id" pens, because Identity uses only "Id", even though it did not work.

Another way is to use DropDownListFor.

@Html.DropDownListFor(model => model.UsuarioId, new SelectList(ViewBag.Usuarios, "UsuarioId", "Nome"))

You tell which property of your model should be used to set the value and which list should fill in the options.

You have missed the fourth and last parameter to indicate which of the items is selected :

var items = db.Users
              .Select(x => new { UsuarioId = x.Id, Nome = x.Nome + " " + x.Sobrenome });

var id = 1; // aqui você coloca qual dos itens é para ficar selecionado

// e aqui você passar o 4 parâmetro para que os item fique selecionado
ViewBag.UsuarioId = new SelectList(items, "UsuarioId", "Nome", id);

This is the example given where the first SelectList is selected and the second is not.

//with selected value specified
var selectItems = new SelectList(brands, "BrandId", "BikeBrand", 2);

//only the items list
var selectItems = new SelectList(brands, "BrandId", "BikeBrand");
