Description Kevin Petit 2017-01-13 12:58:33 UTC
With the latest Xamarin preview I encounter a regression which affects the effects on the Android platform.

If you try to access to the Control property of an effect in the OnDetached method, this will throw an ObjectDisposedException.

protected override void OnDetached()
    Control.Click -= OnClick; // => thrown ObjectDisposedException

This code worked in 2.3.3 and I think the regression has been introduced be this pull request : https://github.com/xamarin/Xamarin.Forms/pull/360.
