I have a problem with connection between 2 entities when there is 2 navigations.

to be specific, I have the following classes:

Answer 1

use this Code :

public class TableA
{
    public TableA()
    {
        ListBs = new List();
    }

    [Key]
    public int Id { get; set; }

    public int TableB_Id { get; set; }

    [InverseProperty("TableA_Mains")]
    [ForeignKey("TableB_Id")]
    public TableB MainB { get; set; }

    [InverseProperty("refA")]
    public virtual ICollection ListBs { get; set; }
}

public class TableB
{
    [Key]
    public int Id { get; set; }

    public int TableA_Id { get; set; }

    [Foreignkey("TableA_Id")]
    [InverseProperty("ListBs")]
    public virtual TableA refA { get; set; }

    [Required]
    public string Text { get; set; }


    [InverseProperty("MainB")]
    public virtual ICollection TableA_Mains { get; set; }

}
