I just started looking into Xamarin Forms and couldn't figure if it was just blindly typing xaml or there was a way to preview it. Thanks for the posts.
Yeah, for now you have to type the XAML but a designer is coming. There is a preview of a previewer but I couldn't get the one in VS to do anything. The XS previewer did work for me though. Make sure Android Studio / ADK is updated if only iOS is working.
I've only tried in VS so far. I'll check XS. Thanks.
