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

Question

我正在使用 Xamarin Forms 4.5.0.617 并且想使用 VisualStateManager ( https://learn.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/visual-state-manager ) 在元素被禁用时更改样式。要将其应用于我的所有样式，我必须多次使用 x:Name="Normal"或 "Disabled"或 "Focused"，但 Rider ( https://www.jetbrains.com/de-de/rider/ ) 说 error应用程序运行正常(风格正在改变)，但 Rider 的警告仍然很烦人。

我做错了什么吗？
