Hey @MarkStega is this a regression, or were you trying this out for the first time?

Have you tried adding the build containers package (dotnet add package Microsoft.NET.Build.Containers) prior to publishing? More info here: https://devblogs.microsoft.com/dotnet/announcing-builtin-container-support-for-the-dotnet-sdk/
