Description

I was wondering if it would be possible to add callback support or extension points to the CppWinRT property implementation classes (like single_threaded_notifying_property, etc.).

So, for example, you could execute some code when a property is updated.

Perhaps this could be done using virtual methods or CRTP, although I'm not sure what the best implementation would be. Thanks for any thoughts or input.

Research direction

Start by reviewing the CppWinRT property implementation classes mentioned in the issue, including single_threaded_notifying_property, and trace how property updates are handled. Define the callback or extension-point requirements and evaluate the suggested virtual-method and CRTP approaches; done requires a concrete, maintainable design for executing code when a property changes.
