We are using a Note element which is based on a Adornment template. We are binding the text to the text property inside a TextBlock.
Is it possible to have a element like a MarkDown viewer. Means: If in the edit mode, you can write markdown code. If not in edit mode, it will be shown as formatted markdown.
We don’t have this kind of solution, though it would be possible to implement one if you had a markdown to HTML provider. Edge cases may get quite tricky though. See: HTML Rendering
