Issue Title

System.Windows.Markup.XamlParseException after removing Style definition in App.xaml

General

I'm found an article for building MVVM WPF app here: https://marcominerva.wordpress.com/2020/01/07/using-the-mvvm-pattern-in-wpf-applications-running-on-net-core

Need to download project https://1drv.ms/u/s!Aj5GOysOGfFKl8JVGGa79K0VMW2Fcg?e=dyhVBW

In the App.xaml on lines 17...19 <Style> definition. If remove them, then get an exception

System.Windows.StaticResourceExtension.ProvideValueInternal(System.IServiceProvider, bool)
System.Windows.StaticResourceExtension.ProvideValue(System.IServiceProvider)
MS.Internal.Xaml.Runtime.ClrObjectRuntime.CallProvideValue(System.Windows.Markup.MarkupExtension, System.IServiceProvider)

And inner exception that static resource 'Locator' not found.

Clearing this for triage and investigation. This is definitely a regression from .NET Framework behavior on the same code base.

FYI: @SamBent @vatsan-madhavan

Actually I re-created this project in .NET Framework and I saw the same behavior. I don't believe this is a regression. (See https://github.com/rladuca/WpfNetCoreMvvm)

This bug should be fixed by #8853. For now, you can workaround this issue by adding a dummy item in <Application.Resources>.
