Synchronous implementation of interface that returns Task

Question

Similar to Implementing an interface that requires a Task return type in synchronous code although I\'m curious if I should just ignore the compiler error my situation gener

Answer 1

If you really do want to do the work synchronously, you know that your async method will always run synchronously, and that's desirable in the situation, then by all means, ignore the warning. If you understand what the warning is telling you and feel that the action it is describing is correct, then it's not a problem. There's a reason it's a warning and not an error after all.

Of course, the other option is to just not make the method async and to simply use Task.FromResult to return an already completed task instead. It would change the error handling semantics (unless you also catch all exceptions and wrap them into a task that you return) so at least be mindful of that. If you really want exceptions to be propagated through the resulting Task, it may be worth leaving the method async and just suppressing the warning.
