Self referencing loop in Entity Framework Core models when using InverseProperty

I have the following models:



 public class MasterData

[Key]
public Guid ID get; set;

[Required]
public string Name get; set;

[InverseProperty(nameof(DetailData.MasterData))]
public List<Detaildata> Details get; set;


public class DetailData

[Key]
public Guid ID get; set;

[Required]
public string Name get; set;

[InverseProperty(nameof(ChildData.DetailData))]
public List<ChildData> Children get; set;

public Guid MasterDataID get; set;

[ForeignKey(nameof(MasterDataID))]
public MasterData MasterData get; set;



public class ChildData

[Key]
public Guid ID get; set;

[Required]
public string Name get; set;

public Guid SectionID get; set;

[ForeignKey(nameof(SectionID))]
public Section ChildSection get; set;

public Guid DetailDataID get; set;

[ForeignKey(nameof(DetailDataID))]
public DetailData DetailData get; set;



To make sure that the migration is well generated and to avoid shadow properties, I add the InverseProperty attribute to define both ends of the relationship.



However, when I try to serialize the instances, I get the following exception:




Self referencing loop detected for property 'DetailData' with type
'Models.DetailData'. Path 'Value.Item1.Details[0].Children[0]'.




Well, obviously it is a self referencing loop, as MasterData has a DetailData that has a MasterData navigation object back - as it should be in a navigational relationship.



Unfortunately, I need to serialize these objects.



A workaround would be to mark the InverseProperty properties with the JsonIgnore attribute, but I'm not sure what it would cause in the deserializing side of the project.



What should I do to avoid the self referencing loop without ignoring the navigation properties?
