The finally block is not always be executed in Linux platform.
See the issue opens for https://github.com/dotnet/runtime/issues/67214, when there is an exception thrown in catch block, the finally statement was skipped when running in linux.

This is either a dot.net runtime issue , or a documentation issue that need to be fixed.
