Container builds no longer work with Preview 7

[richlander]

I installed Preview 7. I was trying to validate if https://github.com/dotnet/sdk-container-builds/issues/479 is resolved.

I now need to specify ContainerBaseImage to make it work.

I am building this app: https://github.com/richlander/dotnet-docker/tree/dotnet-8-samples/samples/aspnetapp/aspnetapp

And then if I do, the user is no longer set.

Can you send a binlog? I couldn't replicate on a self-built SDK from the tip of the 8.0.100-preview7 release branch - I built that app using the same command and the generated manifest had the 1654 user. I'll try again with the latest 7 nightly from dotnet/installer in a bit.

Closing as no repro.
