Hi. Can you please provide any example of the false positive boxing report? HeapView is aware of this compiler optimization, no boxing is reported:

Hello 👋

My apologies for the delay in getting back to you.

I believe the false positive may in fact be a positive value after all—we're working on a legacy project in the middle of a highly awkward upwards migration and I think that there's some unsupported movement in the framework and c# version control that may be causing this issue.

Thankfully, that makes it my problem and not yours.

Sorry about that—but thank you for your diligent response. Appreciate your hard work!
