What is the ValueTask equivalent of Task.CompletedTask?

Question

I am implementing IAsyncDisposable which requires me to return a ValueTask, but sometimes my dispose method has nothing to do. How should I return

Answer 1

All structs have a default constructor. The default constructor of ValueTask creates a completed ValueTask:

var completedValueTask = new ValueTask();

Or alternatively:

ValueTask completedValueTask = default;
