Why is the Set and Get static methods not called in XAML?

Question

I set breakpoints on my connected properties SetXXX and GetXXX static methods. In Xaml, I assigned values ​​to an attached property. However, I expected Set or Get calls to be called, but that is not the case. The attached property works as expected, and if I call the SetXXX and GetXXX methods in the code, it will work.

Why methods are not called when dialing from Xaml?
