AvalonEdit in UAP
AvalonEdit needs to be used in a universal annex, looking for a way to put it as close as possible.
There's no such way unless you rewrite the whole thing from scratch. WPF and UAP of the total have only XAML, they are incompatible. UAP is cut from all sides, so it's not real. In short, without options, you can only try to find another control.
