Aviad Regarding private constructors -
1. How does EF Core know that the private constructor is used to initialize the _id field?
2. What happens if we omit the id field from the private constructor?
Thanks -
JeremyLikness @Aviad:
By convention; the `int id` parameter is matched to the `_id` field. If you omit the id field from the private constructor then EF Core will set the field directly. This is totally reasonable, but you’ll have to suppress compiler warnings that the field is never set.
