How to Apply XML Configuration for Removing Specific Attribute Instances in .NET Linker ( NativeAOT )

[dadavadd]

Hello,

I am working on a .NET project and would like to optimize my assembly by removing specific attribute instances using the .NET linker. I have defined the following XML configuration but need guidance on properly integrating it with the linker in a .NET project:

How should this XML be integrated into the .NET project configuration to instruct the linker to remove these attribute instances?

I've used something like this before:

  <ItemGroup Condition="'$(PublishTrimmed)' == 'True'">
    <RdXmlFile Include="rd.xml" />
  </ItemGroup>

However, its also worth highlighting - NativeAOT uses a different format to the linker: https://github.com/dotnet/runtime/blob/main/src/coreclr/nativeaot/docs/rd-xml-format.md,

So I'm not sure if the XML file you have currently will actually work with NativeAOT.

I inserted before the start of the file and compilation completed successfully.

But this did not reduce the weight of the program.😁

I'll admit, I've not really messed with trimming recently - that snippet was just copied from an old piece of code I had lying around.

WinForms does not officially support Native AOT anyway: dotnet/winforms#4649

The native AOT compiler doesn't have any switches (documented or not) to inject this file into compilation and there are no plans to add one. This file format is only for use within the dotnet/runtime repo.

FWIW there is work in progress to make WinForms trimmable.
