Answer 1

public class Parent
{
public int ParentId { get; set; }
public string ParentName { get; set; }
public virtual ICollection<MappingParentChild> parent{ get; set; }
}
public class Child
{
public int ChildId { get; set; }
public string ChildName { get; set; }
public virtual ICollection<MappingParentChild> child { get; set; }
}
public class MappingParentChild
{
public int Id { get; set; }
public int ParentId1 { get; set; }
public int ChildId1 { get; set; }
public virtual Parent pt{ get; set; }
public virtual Child Ch{ get; set; }
}
public class MappingParentChildConfiguration : EntityTypeConfiguration<MappingParentChild>
{
public MappingParentChildConfiguration()
{
ToTable("MappingParentChild");
Property(m => m.Id).IsRequired();
HasRequired(m => m.pt).WithMany(e => e.parent).HasForeignKey(m => m.ParentId );
HasRequired(m => m.ch).WithMany(e => e.child ).HasForeignKey(m => m.ChildId );
}
}
