IRegionAware not available while implementing custom ScopedRegionNavigationContentLoader

[BabuLalSuthr]

Hi Team,

I'm trying to implement ScopedRegionNavigationContentLoader as per https://www.pluralsight.com/courses/prism-mastering-tabcontrol course, but I noticed that IRegionAware is not available in my project

I noticed that IRegionAware is part of Region.Core and I've referenced Prism.Wpf in my project which also depends on Prism.Core.

**I'm using WPF with .Net Framework 4.8, Prism 8

Please let me know if I'm missing anything :)**

Thanks

This issue isn't really surprising as IRegionAware doesn't exist in WPF in Prism 8.1. The move to core was done in Prism 9 and IRegionAware would be there with INavigationAware being provided in Prism.Wpf for backwards compatibility.
