 As shown in the previous example, if `await` is applied to the result of a method call that returns a `Task<TResult>`, then the type of the `await` expression is `TResult`. If `await` is applied to the result of a method call that returns a `Task`, then the type of the `await` expression is `void`. The following example illustrates the difference.
