I'm new to Xamarin, using Xamarin Studio community version 6.1 (build 5441) and Xamarin.Forms version 188.8.131.52.
I'd like to use the new XS feature to preview XAML files, but the previewer doesn't seem to work for any of my XAML files, not even for a new templated content page XAML. On the top of the previewer it reads "Invalid XAML: Sequence contains more than one matching element" (see picture attached).
What am I doing wrong? Many thanks!
