thanks for this post. i cant understand a point.

why did you add

[assembly: XmlnsDefinition("http://www.tsjdev-apps.de/maui/controls",

"SimpleRatingControlMaui")]

and how did you use with

xmlns:controls="http://www.tsjdev-apps.de/maui/controls"

i cant understand why did you write a url and i couldnt define xmlns:control as you
