Maui: ambigious reference in generated code

[softlion]

that happens when ImplicitUsings are enabled in a maui project:

        <ImplicitUsings>enable</ImplicitUsings>

I worked around it temporarily by adding:

global using PropertyChangingEventHandler = System.ComponentModel.PropertyChangingEventHandler;
global using PropertyChangingEventArgs = System.ComponentModel.PropertyChangingEventArgs;
