What's the method signature for passing an async delegate?

Question

I\'ve recently moved back to C# from being in Objective-C land, and the async/await keywords in C# 5 look cool. But I\'m still trying to get a handle on the proper syntax.

Answer 1

If I have a task that I want to be passed but not executed, I can wrap the Task in a Func<>, then call that Func<> to create that task. The await can be used in the normal way.

public class Example {
    public Example(Func toBeExecutedInTheFuture)
    {
        FutureTask = toBeExecutedInTheFuture;
    }

    public async void ExecuteTaskExample()
    {
        await FutureTask();

        // or alternatively

        var myTask = FutureTask();
        // do work
        await myTask;
    }
}
