A production API sometimes hangs under load. You find code calling `.Result` on async methods. What is the risk and how would you fix it?

For example, if a controller calls a service that blocks on _client.GetAsync(...).Result, each request can hold a thread while waiting for I/O. Under load, enough blocked threads can prevent continuations and other requests from running promptly. I would change the service API to return Task, await the dependency, pass cancellation tokens, and add tests around timeout/error behavior. The trade-off is that async migration can touch many method signatures, so I would do it intentionally rather than mixing blocking and async in the same path.
