In C#7, how can I "roll my own" Task-like type to use with async?

QUESTION

In C#7, how can I "roll my own" Task-like type to use with async?

Asked 2018-Jan-16 at 14:54

One of the less-talked-about features of C#7 is "generalized async return types", which is described by Microsoft as:

Returning a Task object from async methods can introduce performance bottlenecks in certain paths. Task is a reference type, so using it means allocating an object. In cases where a method declared with the async modifier returns a cached result, or completes synchronously, the extra allocations can become a significant time cost in performance critical sections of code. It can become very costly if those allocations occur in tight loops.

The new language feature means that async methods may return other types in addition to Task, Task and void. The returned type must still satisfy the async pattern, meaning a GetAwaiter method must be accessible. As one concrete example, the ValueTask type has been added to the .NET framework to make use of this new language feature:

That sounds great, but I cannot for the life of my find any example that doesn't just use the stock ValueTask type. I want to make my own Task-like type. Specifically I want a type that behaves like a Task, but with a more functional style of error handling.

Here is the type I am using for functional error handling in my project:

I couldn't find any good tutorial yet. But you can look at the compiler unittests which create such task-like types (look for "[AsyncMethodBuilder").

The starting point is to create a type and mark it as task-like with an attribute like [AsyncMethodBuilder(typeof(MyTaskBuilder))]. Then you need to define your own MyTaskBuilder type. It must implement a certain pattern (see below). That is the same pattern implemented by the regular AsyncMethodBuilder type which supports regular Task.
