[Mono-dev] FW: [Bug 349875] Dictionary<TKey, TValue> stores values out of order.

I recall reading somewhere that when possible, mono will try to mimic the
behavior of .Net, to make it easier for people to migrate from the later to
the former.  I can't find that reference now, so maybe it's all in my head.

Hi Josh,

Mono is support to follow the MS .net _design_ not the _implementation_.
If the docs don't state that you can depend on the order of the
elements, you shouldn't do so. I consider an app relying on this order
to be buggy.
