Customize "Avalonia Application" title in MacOS

I’ve noticed that when running my project after dotnet publish on MacOS (Catalina), the title “Avalonia Application” appears in the upper bar

Also there is an “About” submenu that opens this dialog:

How can I change this and maybe replace with custom graphics?

@jeffdoolittle App class can have it’s own DataContext You are supposed to initialize it in OnFrameworkInitializationCompleted

1. Set Name property on the Application in your App.xaml
2. Add a customized native app menu to your App.xaml:

  <NativeMenu.Menu>
    <NativeMenu>
      <NativeMenuItem Header="About My App" Command="{Binding AboutCommand}" />
    </NativeMenu>
  </NativeMenu.Menu>

it will replace the default one.

We probably need that in our default app template.
