I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

@tmds Due to lack of time right now, I can't lead on backporting your changes relating to mono and non-portable builds from main to release/7.0, but I will be tracking the backports as they are processed to faciliate that work.

@ayakael - Given .NET 7.0 will be EOL on May 14, 2024 , the bar is high for accepting servicing changes. Can this be closed?

[ayakael]

Absolutely, closing.
