I’ve packaged and published my code generator, including code fixes and a DLL specifically for the attribute that triggers everything. The attribute isn’t available when I add the package to my .NET 8 project.

If I look at the package with NuGet Package Explorer I see this:

The attribute defined in the DLL is public. What am I missing to make it usable?

This is what I have in the project that does the packing:

<PropertyGroup>
    <TargetsForTfmSpecificContentInPackage>$(TargetsForTfmSpecificContentInPackage);_AddAnalyzersToOutput</TargetsForTfmSpecificContentInPackage>
</PropertyGroup>

<ItemGroup>

    <ProjectReference Include="..RegisterWithDi.CodeFixesRegisterWithDi.CodeFixes.csproj" />
    <ProjectReference Include="..RegisterWithDiRegisterWithDi.csproj" />
</ItemGroup>

<ItemGroup>
    <None Include="..README.md">
        <Pack>True</Pack>
        <PackagePath></PackagePath>
    </None>
</ItemGroup>

<Target Name="_AddAnalyzersToOutput">
