(Newbie) invoking child nodes entity framework core : I`m new into this sort of Object programming, do you mind helping me?
I have to invoke the child nodes, but specific fields, but I can`t figure out how, I`ve already looked into a huge amount of places, but it doesn`t seem to work. 

For exmaple, I want just the FirstName in the RepunicAccount, and all the other info from REpunicAccountType, or anything like it.

My DbContext
    
    using System;
    using System.Collections.Generic;
    using Microsoft.EntityFrameworkCore;
    using Microsoft.EntityFrameworkCore.Design;
    using Models.Account;
   
        namespace Models.dbContext {

            public class RepunicContext : DbContext {
                
                public virtual DbSet<RepunicAccount> RepunicAccount { get; set; }
                public virtual DbSet<RepunicAccountType> RepunicAccountType { get; set; }
    
                protected override void OnConfiguring (DbContextOptionsBuilder optionsBuilder) {
                    
                   optionsBuilder.UseSqlServer ("Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=Repunic;Data Source=DESKTOP-        6I8LD45\\SQLEXPRESS_ERICH");

            }
    
                public RepunicContext (DbContextOptions<RepunicContext> options) :base (options) { }
    
                public RepunicContext () { }
    
       }
    }
    
My Model
    
        using System;
        using System.Collections.Generic;
        using System.ComponentModel.DataAnnotations;
        using System.ComponentModel.DataAnnotations.Schema;
    
        namespace Models.Account {
            public class RepunicAccount {
    
            
                public int ID { get; set; }
                public string Email { get; set; }
    
                public string Username { get; set; }
    
                public string Password { get; set; }
            
                public string FirstName { get; set; }
                public string LastName { get; set; }
    
                [ForeignKey ("ID_Type")]
                public int? ID_Type { get; set; }
    
                public ICollection<RepunicAccountType> TipoConta { get; set; }
    
                public DateTime? DataCadastro { get; set; } = DateTime.Now;
    
                public DateTime? DataAlteracao { get; set; } = DateTime.Now;
    
         }
     }

My Child Node

    public class RepunicAccountType {
        [Key]
        public int ID_Type { get; set; }

        public string Descricao { get; set; }

        public DateTime DataCadastro { get; set; } = DateTime.Now;

        public DateTime DataAlteracao { get; set; } = DateTime.Now;

    }

I Have a repository, that is where I do my coding, before putting into the controller, it`s pretty much the same in every place, but I`m going to send the example that I`m trying to use in both places.

       public IEnumerable<RepunicAccount> GetAllByIDType () {

            var data = db.RepunicAccount.Where (a => a.ID_Type != null).Include (p => p.types);
            var type = db.RepunicAccountType.OrderBy (b => b.Descricao);

            return data.ToList ();

  
        }

The problem is, I don`t know how to invoke specific itens nor make anything else than ToList();

So, What should I do? If there is any more info that I can send, just ask me.
