Feature "UI_Xaml" doesn't compile with windows-rs 0.29-git

Problem

There seems to be a change in Vtable struct names.

Note: need to use windows-rs git to pass the missing Debug impl error

Specifically, when using windows-rs version 0.29, I get four different errors related to IVector_abi and IObservableVector_abi.

There was also an error relating to the Debug trait. This was a known problem introduced in windows-rs 0.29, and fixed in 0.30. The crate compiles without error when using windows-rs 0.28.

This should be fixed once windows-app-rs switches over to the new bindgen crate. @riverar

Yep, hoping to close all issues here with a new crate update!
