I don't know Ktorm, so I won't help you with that part, but your problem is caused by type variance. Yes, you are correct, Users can be safely used as IdTable. But that doesn't mean EntitySequence can be used as EntitySequence>. T type parameter of EntitySequence is invariant which means it can't be safely cast neither up nor down.

In order to safely cast EntitySequence to EntitySequence>, T would have to be covariant, so it had to be marked as out parameter. But it isn't.

In fact, by looking at the definition of EntitySequence I believe T could/should be marked as out. Then you could do what you need without problems. Maybe this is just a bug/oversight in Ktorm.

If I'm correct and T could be covariant, then it should be also safe to fix your problem by making an unchecked cast:
