# Steps to reproduce
- Create Xamarin.Forms project
- Setup XAML ResourceDictionary
- Define a value using OnPlatform
- Reference the value in XAML
- Enable XamlCompilation
- Download and run the attached test case
# Using Xamarin.Forms version 18.104.22.16829
Should be fixed in 2.3.0-pre1
I have checked this issue with the XF 22.214.171.124-pre2 and observed that this issue has been fixed and no longer exist with this version of XF. Now user is able to run attached test same successfully without any exception.
This issue has been fixed, hence I am closing this issue.
I have update the Xamarin Forms to 126.96.36.199, but this issue still exist.
I checked this issue with Xamarin.Forms 188.8.131.52 and using attached sample in bug description. and this issue is working fine at my end.
@David, Could you please let me know some more information regarding your issue or Please file a separate bug for the same.
