🔹 LocExtension Class
namespace NoesisApp
Implements a markup extension that supports references to a localization ResourceDictionary.
Provides a value for any XAML property attribute by looking up a reference in the ResourceDictionary defined by the Source attached property. Values will be re-evaluated when the Source attached property changes.
If used with a string or object property, and the provided resource key is not found, the LocExtension will return a string in the format "<Loc !%s>" where %s is replaced with the key.
A Converter can also be specified, with an optional ConverterParameter.
This example shows the full setup for a LocExtension. It utilizes the RichText attached property to support BBCode markup in the localized strings. The Loc.Source property references the "Language_en-gb.xaml" ResourceDictionary below.

This is the contents of a "Language_en-gb.xaml" localized ResourceDictionary:
