Rider Xamarin xaml: "Field Normal is already declared" from VisualStateManager - xaml

Question

I'm using Xamarin Forms 4.5.0.617 and want to use a VisualStateManager (https://learn.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/visual-state-manager) to change the style if an element is disabled. To apply this to all my styles, I have to use the x:Name="Normal" or "Disabled" or "Focused" multiple times, but Rider (https://www.jetbrains.com/de-de/rider/) says error
The app runs correctly (style is changing) but the warning of rider is still annoying.
Am I doing something wrong?

You are not doing anything wrong. This is a confirmed known issue with Rider/ReSharper. I have already reported it here.
What I can suggest is that you upvote the issue and/or write a comment, so that they can escalate it and fix it quickly.
