Maybe remove the Viewbox and always use the Canvas in a Viewbox in my own view? Is it more effective to use a Label (or some other control)? Should I use a ContentPresenter and set its Content property and set the Canvas x:Shared='false'? What is most resource effective way of showing this element?

Let's assume I have wrapped it in a ResourceDictionary and given the Viewbox a x:Key='SquareIcon' value. Is there a way to have only one ResourceDictionary where I can import all of these XAML files? The image will be shown multiple times, for example in a ListViewItem or any other element that has an ItemsSource. This is annoying because I cannot edit the file in Inkscape anymore without having to remove the ResourceDictionary before. To use this file I'd normally have to wrap it in a ResourceDictionary. When you create an image with Inkscape and save as XAML you'll only have a Viewbox inside an XAML. There are many articles on the internet but not many of them show the pro and cons of each solution.

This question aims to be a best practice on how to use images created with Inkscape and saved as XAML.
