That was pretty complicated, but I think it’s worth seeing each step spelled out. Notice that every single line of my code was executed by the UI thread. The IO completion port thread only ran long enough to Post an instruction to the UI thread, which ran the second half of both my methods. Choosing Not to Use SynchronizationContext Each implementation of SynchronizationContext performs Post in a different way. Most of them are relatively expensive. NET will not use a Post when the captured SynchronizationContext is the same as the current at the time of the Task’s completion.

Let’s look at the body of the method. Task; Notice that the method isn’t marked async; we’re creating a Task manually, so we don’t want the compiler to generate one for us. The TaskCompletionSource creates the Task, and makes it available as a property for us to return. We can later use the SetRe sult method on the TaskCompletionSource to make the Task complete. Because we’ve followed the TAP, our caller can just await the user’s permission. The call is very neat. if (await GetUserPermission()) { ....

I know that the delay can never throw an exception, so I don’t need to deal with it. Exception); } } Obviously, exactly what to do here depends on your strategy for handling exceptions. By attaching this using ContinueWith, I’ve made sure that whenever the original Task does finish, however far in the future that may be, the code to check for an exception is run. Importantly, this doesn’t hold up the main execution of the program, which already did whatever it needed to do when the timeout expired.
