Unable to Resolve Symbol 'LightGray' in UNO Platform

[ShahrukhYousafzai]

Current behavior

When using the UNO Platform, the symbol 'LightGray' is not recognized, resulting in error:

The symbol 'LightGray' is not recognized, but build works however these errors are pretty annoying as program do compiles properly

Expected behavior

The LightGray color should be resolved correctly, as it is a standard predefined color.

How to reproduce it (as minimally and precisely as possible)

Create a new UNO Platform project.
Try using "LightGray" or any Color in XAML.
Observe the error in the build output.

Thanks for the report.

This is indeed a known color:

uno/src/Uno.UI/UI/Colors.cs

Line 494 in 212316d

public static Color LightGray => _lightGray ??= FromInteger(unchecked((int)0xFFD3D3D3));

This looks like a Rider IDE issue that we cannot fix without help from the Rider team. It's likely best to open an issue on their tracker.

I do get the same errors about color on visual studio as well. And I do not get this LightGray or any color error on any other type of project. It happens only on UNO Platform project no matter if I use Rider or Visual Studio as you can see in the screenshots of both IDEs

Thanks. Could you show a screenshot of the error you're seeing in visual studio?
