Recommend review with whitespace diffs off because converting ordered/unordered helpers to local functions caused indentation changes.

@jeffhandley @ericstj @jozkee please take a look at this approved API implementation so it doesn't miss the .NET 10 release.

• [nitpick] Fields in C# tests typically use camelCase or are declared as properties. Consider renaming IsOrdered to _isOrdered or exposing it as a protected property protected bool IsOrdered { get; set; } to follow naming conventions.

protected bool IsOrdered = false;

@PranavSenthilnathan feel free to take over and adjust this as you see fit. The PR is functionally complete, and I addressed all your feedback a month ago but now you're requesting a complete overhaul?

@jkotas could I get an authoritative review here? I'd like to avoid going back and forth with shifting feedback.

You have the right people CCed here. I am not the right person to ask for an authoritative review on this one. https://github.com/dotnet/runtime/blob/main/docs/area-owners.md has the list of folks and aliases to tag for each area.

Not sure why pushing to kasperk81:main automatically closed this PR... I'll create a new PR with the changes I tried to push.
