Description

It seems the issue described in #18704 is not fixed.

• Setting any property (Bindable or regular) with the ObsoleteAttribute in XAML should lead to a warning during compilation (this currently works). Additionally, the warning should include the text specified in the ObsoleteAttribute (does not work).
• If the ObsoleteAttribute has the error parameter set to true, it should result in a compilation error (does not work).
• The above rules should apply when attempting to set a property in styles (does not work).
• The above rules should also apply to entire classes (does not work).

Steps to Reproduce

1. Download the attached repo
2. Checkout MainPage.xaml and MaingPage.xaml.cs
3. Build the project
4. Check the build output
