Add Intellisense for C# Markup resources.

[mcNets]

I was trying/learning C# Markup language and I realized that now, when you create for example a new Brush, you get no Intellisense of the current static o themed resources.

this.Background(ThemeResource.Get<Brush>("ApplicationPageBackgroundThemeBrush"));

That makes it more difficult to use than the usual XAML code.

Maybe it would be possible, perhaps using a source generator, to create some static Enum with the name of all existing resources in the app. Something like:

this.Background(ThemeResource.Get<Brush>(AppBrushes.ApplicationPageBackgroundThemeBrush));

It would be great to have different Enums depending on the type of resource. (Brush, Color, BitmapImage, ...)

We currently have this mapped for those that are using the Material Theme you can read a little more on it in the docs.

new Button()
    .Style(Theme.Button.Resources.Styles.Elevated)

Note that this also works with other values in the theme such as colors & brushes
