I am not the expert (Hello @adambien ?) but the transaction that the request handling started in will stay open until the asynchronous method returns. Not sure what the implication on the request-handling thread is. Is the transaction 'owning' that thread or is it detached?
Just wondered whether/how executing the asynchronous (long running) method in the same transaction (the default) will affect the request handling thread - and whether it leads to the same blocking that actually is intended to be avoided.
