In languages that have a return value, you can bind a function output binding to the return value: In a C# class library, apply the output binding attribute to the method return value. This is not a direct answer to old question, but for others searching: "Normally" you shouldn't do this, but sometimes you need to match a library API so you can use a wrapper function like below: private async Task WrapSomeMethod(string someParam) { //adding .ConfigureAwait(false) may NOT be what you want but google it. In previous posts we learned about functions.
