Downgrade C++/WinRT if you want this, this is a breaking change in the C++ projection. (Edited to be consistent with the post by @sylveon.)

This is not a bug, it's an intended change. ProtectedCursor is protected so it should've never been exposed publicly in the first place.

The proper way is to do it like in C#, by inheriting from the UI element.

You can also do element.as<IUIElementProtected>().ProtectedCursor() to minimize code changes on your end, but it's more of a workaround/hack.

There's a bigger question about whether or not this member should be made public in a future WASDK update (so that C# users can also enjoy being able to set the cursor without inheritance), or a better API for setting the cursor introduced.

thanks for the workaround. yeah it would be best for there to be public API to change cursors. I can close this if you think that a public API should be tracked in a different issue.

A public UIElement.Cursor property remains a desired API addition on the backlog (internal tracking item). We don't have a timeline for that currently. I don't see a "feature proposal" tracking that in this repo; feel free to log that, if desired.
