You also have to understand that shoving async down our throats is part of the philosophy of how aspnet core and kestrel (built ontop of libuv) is implemented: the whole stack is built to run async and with DI in mind. aspnet core itself uses the same DI system to manage itself. No part of aspnet core is built to run synchronous. Its all async all the way down.
