The async-scenarios documentation motivates `Task.Run` by keeping a UI thread responsive; in ASP.NET Core there is no such thread, and a request handler that does `await Task.Run(() => Compute())` releases one thread-pool thread while borrowing another for the same work, so the pool's capacity is unchanged, a queueing step and a context switch are added, and starvation arrives at exactly the same load. On a server, CPU-bound work in a request should simply run synchronously in the handler; `Task.Run` earns its place there only to fan one request's CPU-bound work across cores, and even that competes with every other request for the same cores. I would restrict the bullet to client applications and state that in ASP.NET Core `Task.Run` neither adds capacity nor makes a synchronous API asynchronous.","created_at":"2026-09-16T15:45:21.232797+00:00","kind":"counterargument"}],"next_cursor":null}
