#1816
Hello,
Im using fo-dicom, and fo-dicom.json in version 4.05 at hospital. Latelly I wanted to switch to new versions of fo-dicom, and after upgrading it to 5+ (no matter whitch wersion, the first 5 or the latest) I'm keep getting json serialization error:
"Newtonsoft.Json.JsonSerializationException: Self referencing loop detected for property 'Tag' with type 'Dicom.DicomTag'. Path '[0].Tag.DictionaryEntry'."
I use Newtonsoft.Json serialization with "JsonDicomConverter" to serialize "DicomDataset" (received from C-Find action, when asking for ModalityWorklistInformationModelFind). I usually store result of serialization in DataBase, to handle it later - when Im using this data to sign the surgery files uploaded to PACS server.
Please help - I tried to fix it alone, but with no acceptable results.
The code (it works with Fo-Dicom ver 4.05, but after migrating to 5+ it keeps throwing exceptions): var serializedDataset = JsonConvert.SerializeObject(dataSet, new JsonDicomConverter(true));
The full stack trace of the exception:
Newtonsoft.Json.JsonSerializationException: Self referencing loop detected for property 'Tag' with type 'Dicom.DicomTag'. Path '[0].Tag.DictionaryEntry'.

The DataSet contains default Tags, added to C-Find request when creating Worklist querry.
I already tried to create my own C-Find request, with less Tags, but the exception always occour, even I would keep only base Tags like Patient Name, Accession Nummber etc.
