Description Paul Anderson 2017-05-02 11:59:41 UTC
We are using following code snippet for converting a view from Xamarin.Forms to native iOS/Android.

internal static IVisualElementRenderer Convert(Xamarin.Forms.View source, Xamarin.Forms.VisualElement valid)
            IVisualElementRenderer render = (IVisualElementRenderer)source.GetValue(RendererProperty);

            if (render == null)
                render = Platform.CreateRenderer(source);
                source.SetValue(RendererProperty, render);
                if (valid != null)
                    var p = PlatformProperty.GetValue(valid);
                    if (p != null)
                        PlatformProperty.SetValue(source, p);
                        IsPlatformEnabledProperty.SetValue(source, true);

            return render;

After updating to the latest Xamarin.Forms version( we were unable to access the PlatformProperty.GetValue() method.

 Is that the  property has been removed and Is there any other way to achieve our requirement ?

Can you please upload a small reproduction to see exactly what you're doing aside from that code being used? This worked for you in 2.3.4?

This issue will be closed due to a lack of response for over a month. Please reopen this and attach a minimized reproduction project if the issue still exists as of the latest prerelease or nightly build.
