This would help the exporters/processors to quickly look up the suppress_instrumentation flag without a hash lookup.

  • We should have XML comments here. Important spot :) Not sure exactly how to word it though?

  • Should context be in the prop name? SuppressInstrumentationOnCurrentContext? Trying to hint to users what it is doing.

Good catch, will add it.

Not sure, the proposed name seems too long 😅
Perhaps the XML comment should address this?

What if it wasn't exposed as a bool? Something more like log scope: public IDisposable SuppressInstrumentation()
Which is to say, return an object that sets the bool to true on ctor, sets it to fault on dispose?

I believe this is what @reyang was proposing in the PR description. I think I do like the disposable idea. I'm currently playing with this implementation and I thing this would make things read nicer.

Yeah, @alanwest is helping on that part in a separate PR ❤️
