My sample json { "ID": 1, "Account": { "ID": 1, "Username": "username", "Password": "123", "CredenticalID": 1 }, "FacebookAuthentication": { "ID": 1, "Name": "fbName", "Token": "1213", "CredenticalID": 1 }, "GoogleAuthentication": { "ID": 1, "Name": "ggName", "Token": "1213", "CredenticalID": 1 }, "Guest": { "ID": 1, "GuestId": "GuestId", "CredenticalID": 1 }, "UserID": 1 }

The result: _class Credentical { int? iD; Account? account; FacebookAuthentication? facebookAuthentication; FacebookAuthentication? googleAuthentication; Guest? guest; int? userID;

googleAuthentication field in Credentical class was generated with wrong type
