Zhiyi Zhang (@zhiyi) commented about dlls/wintypes/propertyset.c:
struct propertyset { IPropertySet IPropertySet_iface;
- IObservableMap_HSTRING_IInspectable IObservableMap_HSTRING_IInspectable_iface;
- IMap_HSTRING_IInspectable IMap_HSTRING_IInspectable_iface;
- IIterable_IKeyValuePair_HSTRING_IInspectable IIterable_IKeyValuePair_HSTRING_IInspectable_iface;
I would prefer it if you add these interfaces one by one.
