How to map an domain entity which has no public parameterless constructor

[Ewerton]

In DDD some advise to not provide any way of creating an object with an "invalid or unpredicted" state, that's why we do not expose any public parameterless constructor in our domain entities.
So I have this domain object

 public class TodoTask
 {
     public long Id { get; set; }
     public required string Name { get; set; }
     public string? Description { get; private set; }

     private TodoTask() // private to not create an "invalid state" object
     {
     }

     [SetsRequiredMembers]
     public TodoTask(long id, string name, string description)
     {
         Id = id;
         Name = name;
         Description = description;
     }

and also, I have the following DTO

public record TodoTaskDto
{
     public required long Id { get; set; }
     public required string Name { get; set; }
     public string? Description { get; set; }
}

And now I want to map from one to another, like this

 [Mapper]
 public partial class TodoTaskMapper
 {
     public partial TodoTaskDto ToDto(TodoTask todoTask);
     public partial TodoTask ToTodoTask(TodoTaskDto todoTaskDto); // <-- Error RMG013 TodoTask has no accessible constructor with mappable arguments
 }

How can I solve this?

Currently, you can't. What you need is #997 to enable private constructor access from Mapperly.
