Protected ctor does not get called


In the example below, why does the public ctor get picked instead of the default protected ctor?
This will fail because of this - it will succeed if the default ctor gets picked

void Main()

public class Tagged : Tag
    protected Tagged() : base() { }

    public Tagged(Tag tagDefinition)
        Id = tagDefinition.Id;
public abstract class Tag
    public int Id { get; set; }

Because Json.NET defaults to using public. Read the documentation if you want to see how to change that.

The only thing I could find in the docs is JsonConstructor which only allows to do it on a per-object basis.

I'd like JSON.NET to use the default ctor in all cases, regardless of its visibility - is this possible to specify?

Never mind, just found ConstructorHandling.AllowNonPublicDefaultConstructor
