Breaking code documentation is missing breaking change 'DefaultColumnNames' is inaccessible due to its protection level"

[PeterPann23]

Hi,

I have updated to the latest preview to see what's coming and I noticed that all locations using
DefaultColumnNames throws an error stating that it is no longer available due to its protection level. I did not find this mentioned in the docs/migrations/breaking-changes-1.0.0-preview.md

You're right. I just updated that breaking change in that doc.
The team decided on making that utility class internal. See the PR here:
dotnet/machinelearning#2842

If you have any comment/feedback about it, please do so in that PR, ok? 👍

Closing this issue for the reasons above.
