Summary

Dealing with large files in Web API and – for that matter – in any HTTP scenario, can be a bit troublesome and sometimes even lead to disastrous service outages, but if you know what you are doing there is no reason to be stressed about anything.
On the other hand, request/response stream buffering is one of those areas where Web API still drags a baggage of System.Web with it in the web host scenarios, and therefore you need to be careful – as not everything you can do in web host, can be achieved in self host.
