#62090 (review)

It looks like based on the linked discussion we need to put this in a holding pattern until the discussion in #62090 (review) is resolved.

#62090 is now merged, I rebased my branch on top of it.

For the OTEL semantics, according to open-telemetry/semantic-conventions#2642 (comment), adding methods known to the instrumentation is ok and since QUERY is now supported it would still follow conventions.

Also, I did not find any tests specific to the known HTTP methods, should I just add new ones or this is good to go?

/cc @JamesNK might be in your wheelhouse. Was added to SemConv by open-telemetry/semantic-conventions#2643 for v1.38.0.

@halter73 Could we get your review on this? Would be good to get it merged sooner rather than later so we can do validation downstream in open-telemetry/opentelemetry-dotnet-contrib with preview builds.

@doominator42 Would be good to add QUERY to this test:
