Should _BuildOutputInPackage be public?

[olivier-spinelli]

I have a simple need: I need to generate the runtimeconfiguration.json for a class library (a tool requires it), but don't want it to appear in the NuGet package.

I ended up with this, using the "private" _BuildOutputInPackage:

 <Target Name="RemoveRuntimeConfigFileFromPackedFiles" BeforeTargets="GenerateNuSpec" >
    <ItemGroup>
      <_BuildOutputInPackage Remove="$(ProjectRuntimeConfigFilePath)" />
    </ItemGroup>
  </Target>

I didn't find any other way (this is not part of the @(Content) so the Pack metadata is useless, I failed to spot a public ItemGroup that would do the job.

I think I may not be the only one.

Did I miss something?
