I understand that you want the return of the Id of an object, if the Id column is integer and IDENTITY .

Considering that the mapping was done within the framework of the Entity Framework:

[DisplayColumn("Nome")]
public class Fruta
{
    [Key]
    public int FrutaId { get; set; }
    [Required]
    public String Nome { get; set; }
    ...
}

Just insert and read the object id:

var fruta = new Fruta { Nome = "Laranja" };
context.Frutas.Add(fruta);
context.SaveChanges();

var idDaFruta = fruta.FrutaId;
