I've added the Syncfusion trial version using the Xamarin Component store. Then I tried the 'using' directive to reference SfChart.
But it doesn't work. I can reference Syncfusion.SfChart.XForms no problem. I also have the same problem with other widgets.
I can always reference the XForms part normally, but not the Android part. I also can't reference Syncfusion.SfChart.XForms.Android.
I have the same problem with all the other components, so I put it under general
I attached an image as demonstration.
(Note: I also tried installing Syncfusion Xamarin manually and then adding the Andorid refence - still doesn't work)
