Research direction

Open non-lts/Dockerfile at the six referenced lines (4, 10, 15, 23, 26, and 21) and inspect each image tag targeting net471. Update those images to net48 or the current release, then confirm all six entries no longer use the unsupported target; if any must remain, review the documented dotnet-versionsweeper.json ignore configuration instead.

Description

The following Dockerfile(s) target a .NET version which is no longer supported.
This is an auto-generated issue, detailed and discussed in dotnet/docs#22271.

Consider upgrading Dockerfile images to either the current release, or the nearest LTS TFM version.

If any of these Dockerfile(s) listed in this issue are intentionally targeting an unsupported version,
you can optionally configure to ignore these results in future automation executions.
Create a (or update the) dotnet-versionsweeper.json file at the root of the repository and
add an ignore entry following the
globbing patterns detailed here.
