@danmosemsft Can you check and make sure nothing in here is needed for 3.1 p1?

[dotnet-maestro-bot]

❌ Uh oh, this pull request could not be updated automatically. New commits were pushed to release/3.0, but I could not automatically push those to merge/release/3.0-to-release/3.1 to update this PR.
You may need to fix this problem by merging branches with this PR. Contact .NET Core Engineering if you are not sure what to do about this.
