How to access context via MarkpExtension.ProvideValue

[mwpowellhtx]

Apparently with MarkupExtension.ProvideValue being the key, in particular IServiceProvider serviceProvider...

Need some basic guidance on how to gain insights into a particular usage context, the control, the outermost XAML element, and any resources that might be had in this context, i.e. Control.Resources, Windows.Resources, if at all possible.

For background, I am scanning through the Learn docs, but nothing is really standing out as an obvious this is the way moment, to be honest. More probably, I have just not asked the right question yet, but I am getting there.

To clarify, in the context of a MarkupExtension usage, my goal is to identify, if possible, the nearest possible <*.Resources/>, either the control resources, or outermost <Window.Resources/>, etc, possible, of a particular type. Surely something like this must be possible given the correct service provider, navigating the XAML element plumbing at the CSharp object level.

I wonder, for instance, is IAmbientProvider something of interest, considering ResourceDictionary supporting FrameworkElement.Resources is annotated:

[System.Windows.Markup.Ambient]
public System.Windows.ResourceDictionary Resources { get; set; }

Much of that API is geared toward knowing the key, usually a string, via indexing operator, or FindResource method. However, I do not necesssarily want to know the string, rather, identify the value by its type.

Sorry I missed this question. Did you see how StaticResourceExtension does it?
