Could a compiled application read and render XAML at runtime? I guess that it couldn't but, since that subject is of extreme importance to me (and to other people where I work), I ask the question anyway.
We work on a large Silverlight application that allows to edit yearbook page layouts (a kind of Adobe InDesign on the Web) and saves them in XAML format; the XAML content is then processed at our place to produce PDF files that we print. Since the support for Silverlight is about to end, we want to convert the application to HTML5/JS. Your development framework looks interesting; if using it allowed the application to work with XAML documents, it would become the obvious choice for the future development of our application.
