Using IMap/IObservableMap as ItemsSource for ListView

[Holo-Krzysztof]

I've described the problem on StackOverflow already and also filed a docs issue before finding out that the docs are actually technically right.

To summarize, I can bind an IVector<T> to a ListView control just fine, but when I substitute it with an IMap<K,V> or IObservableMap<K,V> I get exceptions. As I've found out this is due to IMap<K,V> not implementing IIterable<IInspectable> which is what the ItemsSource property expects.

However, it is possible to use Dictionary in C# and everything works just fine, so there must be something else happening here. Do you know how to CLR handles this and how I can accomplish this in C++?

This question is specific to the Xaml API. I suggest bringing it up on the Xaml issues page:

Here is a simple implementation that implements IIterable<IInspectable>, as has been suggested by the Xaml team. If someone can test this against Xaml and confirm that this provides the desired behavior then we can update C++/WinRT to do the same.
