Export the GeneratedContainer item

[scrocquesel-ml150]

I want to write down to a file, the list of generated container image. I saw that PublishContainer is somehow collecting evidence in the GeneratedContainer but I didn't succeed in using it.

I tried something like

      <Target Name="WriteContainerAssets" AfterTargets="PublishContainer">

          <ItemGroup>
            <GeneratedContainerJson Include="@(GeneratedContainer)">
                    <Line>{
                &quot;Manifest&quot;: &quot;%(Manifest)&quot;,
                &quot;Configuration&quot;: &quot;%(Configuration)&quot;,
                &quot;ManifestDigest&quot;: &quot;%(ManifestDigest)&quot;,
                &quot;ManifestMediaType&quot;: &quot;%(ManifestMediaType)&quot;
              }</Line>
              </GeneratedContainerJson>
          </ItemGroup>

          <WriteLinesToFile
            File="container.json"
            Lines="@(GeneratedContainerJson->'%(Line)')"
            Overwrite="true"
          />
      </Target>

But GeneratedContainer is always empty. Any clues ?

Nevermind, the project targets .net8.0. GeneratedContainer was introduced in net9.0
