C# Elasticsearch 8.0.3+ 400 Bad Request media_type_header_exception

Hi, @KoalaBear.

If this works locally but not when deployed, possibly something in the way it is deployed is breaking the logic which loads the version from our assembly info. We saw this for a user who was creating a single DLL causing the version lookup to fail. Are you packaging your application in an unusual way that might cause a similar behaviour?
