Scenario

I have e.g. abstract class called Quiz and two children of this Quiz: SingleAnswerQuiz and MultipleAnswerQuiz. I map this model into Table per hierarchy with entity framework.

Problem

Is there any way to change one SingleAnswerQuiz type to MultipleAnswerQuiz? I do not want to delete single quiz and create multiple with data of deleted quiz. I want to have the same id after "mapping". Should I use Discriminator?

Can you provide the code defining the objects? – Richard Boyce Nov 20 '18 at 16:13
it is not necessary, it is just kind of proof of concept – zolty13 Nov 21 '18 at 06:57
