@Tim - just sent you an email. Thanks for looking at this!
I'm ******* my head against a wall trying to port a well known WPF control library over to UWP. We were cross-platform to Silverlight/WPF so were previously able to implement MultiBinding, DynamicResource and x:Static all as MarkupExtensions. This made our lives much much easier.
Adding even just a very simplistic version of MarkupExtension to UWP would make the impossible, possible here. Many of the UWP quirks we've worked around but this one really is causing us a headache.
Do please give us an update as to expected delivery date. I know it's under investigation now but I cannot emphasise enough how much this would mean to us for supporting the platform.Andrew Thompson supported this idea ·
