Feauture layer has been added it's showing up on the map.
nothing on popup.
Can you share your code (e.g. XAML) where you've configured the UI to display the contents of the Popup?
The popup is working mumps which is downloaded.
not working on feature layer.
Is `result?.Popups?.FirstOrDefault() is Popup` true? Does that feature layer have popups configured?
how can I share my code
result?.Popups?.FirstOrDefault() is Popup giving null.
Did you define a popup definition on your feature layer? Otherwise that collection would be null.
I'm looking at this code https://developers.arcgis.com/net/wpf/sample-code/show-popup/
do you have a example popup definition.
Popupdefinition still the same.
