First of all. Thank you, for this solution.
For HasMany relationships, what about something like:
_context.Entry(entity).Collection(relation).Load();
instead of:
_context.Entry(hasManyPointer).ReloadAsync();

Thanks for the suggestion, I wasn't aware of the .Collection api. I think I like the approach I ended up taking better. The reason is that we should end up with a single SQL request that uses JOIN to load all the relationships rather than reloading each included relationship individually. I'll review it again later tonight to verify the difference.
