This file seems to be generated and it says at the top of the file to not edit it manually: https://github.com/dotnet/wpf/blob/main/src/Microsoft.DotNet.Wpf/src/PresentationCore/System/Windows/Media/Generated/ImageDrawing.cs#L7.

I thinkg that this field is generated from this entry in the xml: https://github.com/dotnet/wpf/blob/main/src/Microsoft.DotNet.Wpf/src/WpfGfx/codegen/mcg/xml/Resource.xml#L3426.

You can try removing the entry in the xml and then running the codegen (I haven't tried running the codegen but you can take a look at the readme). It also generates some C++ code so this field might be used elsewhere.

Thank you @ThomasGoulet73 for highlighting the catch.
Yes for generated code, editing manually is not a good idea. Will take a deeper look at XML and all generated source code.

Haha, I should've paid more attention
