The problem with that is always what the frontend kids call "responsive" these days. The D&D editor doesn't infer a layout, so when you resize stuff stays the same or everything resizes equally, which is terrible.
I think the XAML approach was ideal, where you had a design view that showed a rendering of your view and allowed to make property changes and D&D controls, but also had the source to properly use grids and other layout managers to align and resize components.
