Task.FromResult would be the most direct. It also includes inbuilt results for a few common integers etc. However, if your value is not an "obvious" value (and won't have inbuilt handling) but is likely to be returned often in your scenario - then you can create your own cached result in a field (maybe static if appropriate) - but it is important to cache the Task, not the result itself.l - otherwise just use Task.FromResult each time.
