Question

Is there a promise interface for the Task class like jQuery’s deferred’s promise method?

Answer 1

The TPL, and the Task class, are very different than jQuery’s promise.

A Task is actually effectively more like the original action. If you wanted to have something run when the task completed, you’d use a continuation on the Task. This would effectively look more like:

Task someTask = RunMethodAsync();
someTask.ContinueWith( t =>
{
   // This runs after the task completes, similar to how promise() would work
});

If you want to continue on multiple tasks, you can use Task.Factory.ContinueWhenAll or Task.Factory.ContinueWhenAny to make continuations that works on multiple tasks.
