@Varorbc This is an issue with the SDK for .NET Framework projects. I’ve filed https://github.com/dotnet/sdk/issues/3639.

Workaround

You can work around the issue by adding this to your csproj:

<PropertyGroup>
  <EmbeddedResourceUseDependentUponConvention>true</EmbeddedResourceUseDependentUponConvention>
</PropertyGroup>

Unfortunately, in 3.0 Preview 9 you’ll then hit https://github.com/microsoft/msbuild/issues/4695, but this should be fixed in the next release.

I’m targeting net461 and the workaround with setting EmbeddedResourceUseDependentUponConvention is not working.

Instead i’m using:

<ItemGroup>
    <EmbeddedResource Update="**\*.resx">
        <DependentUpon>$([System.String]::Copy('%(FileName)')).cs</DependentUpon>
    </EmbeddedResource>
</ItemGroup>

which seems to work just fine.
