XC0009 Error: No Property, BindableProperty, or Event Found for Border Class in .NET MAUI

Question

I am encountering an XC0009 error while working with .NET MAUI and would appreciate any assistance in resolving this issue.

Screenshot 1:

Screenshot 2:

In Screenshot 1, while writing the 'Shadow' property for the "Border" class, the Build + IntelliSense in Visual Studio 2022 recognizes the property correctly. However, in Screenshot 2, when attempting to run the program, I receive the error XC0009: "No property, BindableProperty, or event found for 'Shadow' or mismatching type between value and property."

I am using .NET 9 SDK and would like to implement the 'Shadow' property in my project. Any guidance on how to resolve this would be greatly appreciated.

Hello,

receive the error XC0009: "No property, BindableProperty, or event found for 'Shadow' or mismatching type between value and property."

You cannot use the Shadow by setting Thickness.

To add a shadow to a control, set the control's Shadow property to a Shadow object whose properties define its appearance like following code.

<Border StrokeThickness="2" Stroke="Green" BackgroundColor="AliceBlue" Padding="20" >
 
   <Border.Shadow>
      <Shadow Brush="Black"
            Offset="20,20"
            Radius="40"
            Opacity="0.8" />
    </Border.Shadow>

    <Border.StrokeShape>
            <RoundRectangle CornerRadius="15"></RoundRectangle>
    </Border.StrokeShape>
       ...
</Border>

Here is a doucment about how to create shadow.

By the way, please do not share your code or error with screenshot(it is inaccessible), you can paste you code or error directly here.
