I have an inheritance chain, and in some case it’s not resolved correctly:
public class TestOptionProperty : MyOptionProperty<BugEnum>
{
public TestOptionProperty()
: base(
"Test",
new BugOption<BugEnum> { Value = BugEnum.A },
new List<BugOption<BugEnum>>()
) { }
}
I’m not sure but i think that enum is case in this case…
I did less complicated test and it’s working properly…
If i try to fix that with implicit operator i get crash deeper…
