Hi!

Just to confirm. For the collection types, e.g. IVector, IMap. Currently there is no c++20 ranges support, right?

That's right - I don't yet know what would be involved in lighting that up. If you have, feel free to outline an approach and we can talk it through.

It seems that the issue is that std::ranges::_Begin::_Has_ADL doesn't matches for cppwinrt types, meaning that std::ranges::begin is disabled, this making the std::ranges::range concept that everything else relies upon not match.

The latest version supports C++ ranges now @zh4ui. There are errors in the IDE, but this is caused by IntelliSense and might be fixed soon™ (see microsoft/STL#1621).
