Mixing
Polymorphic Code-First Models and Querying
0
I'm trying to build a survey system and want to use inheritance on the Question model, using code-first migrations.
public class MultipleChoiceQuestion : Question {
public bool AllowMultipleSelection { get; set; }
public List<MCQOption> Options { get; set; }
}
Even if I add another DbSet<MultipleChoiceQuestion>, it doesn't appear in the migrations. What am I doing wrong?

It doesn't add anything that would result in additional columns, so another table isn't needed (presumably theMCQOptionhas a FK back toQuestion)

@juharr guess I oversimplified my sample code. Fixed it to solve the case you mentioned.
