How to match it? HasOne x Links

Question

I need to do the “One by One” comparison, and I have some doubts. I have classes:

public class DocumentType {    
    public virtual int Id { get; set; }    
    /* othes properties for documenttype */  
    public virtual DocumentConfiguration Configuration { get; set; }
    public DocumentType () { } 
}

public class DocumentConfiguration {
   public virtual int Id { get; set; }
   /* some other properties for configuration */   
   public virtual DocumentType Type { get; set; }

  public DocumentConfiguration () { }
}

A DocumentType object has only one DocumentConfiguration, but it does not inherit, it is only one after another and unique to separate properties.

What should be my display in this case? Should I use links or HasOne? Can anyone give an example?

When I load the DocumentType object, I would like to automatically load the Configuration property (in the Type document).

Thanks a lot guys!

Greetings

public class DocumentConfiguration {

   /* some other properties for configuration */   
   public virtual DocumentType Type { get;  protected internal set; }
