SuperObject Serializes Private Variables instead of Properties

Question

I have the following code that serializes a dynamic array of classes. For some reason SuperObject serializes on the private variables instead of the class property names. Can anyone please advise how to fix this behaviour in SuperObject?

class function TJSON.AsJSON<T>(AObject: T; Indent: Boolean = False): string;
var
  Ctx: TSuperRttiContext;
begin
  Ctx := TSuperRttiContext.Create;
  try
    Result := Ctx.AsJson<T>(AObject).AsJSon(Indent);
  finally
    Ctx.Free;
  end;
end;

type
  TMyClass = class
  private
    FName_: String;
    FAge_: Integer;
  public
    property Name: String read FName_ write FName_;
    property Age: Integer read FAge_ write FAge_;
  end;

procedure TFormTest.Button27Click(Sender: TObject);
var
  MyClassArray: TArray<TMyClass>;
  MyClass1, MyClass2: TMyClass;
begin
  MyClass1 := TMyClass.Create;
  MyClass1.Name := 'Joe';
  MyClass1.Age := 10;

  MyClass2 := TMyClass.Create;
  MyClass2.Name := 'Dan';
  MyClass2.Age := 13;

  SetLength(MyClassArray, 2);
  MyClassArray[0] := MyClass1;
  MyClassArray[1] := MyClass2;

  Memo1.Text := TJSON.AsJSON<TArray<TMyClass>>(MyClassArray);
end;

The above code generates the following JSON:

[{"FName_":"Joe","FAge_":10},{"FName_":"Dan","FAge_":13}]

what I am after is the following JSON:

[{"Name":"Joe","Age":10},{"Name":"Dan","Age":13}]

I think it's not possible at this time and that you probably hit this issue. Even Delphi XE2 Datasnap serializes private fields at JSON marshalling and in my view it's just a consequence of a deeper visibility given to the new extended RTTI without considering the limits.
