How is async method implemented?

You can use await Task. Yield(); in an asynchronous method to force the method to complete asynchronously. Insert it at beginning of your method and it will then return immediately to the caller and complete the rest of the method on another thread.

How can we make asynchronous method calls using delegates?

When you call a delegate synchronously, the Invoke method calls the target method directly on the current thread. If the BeginInvoke method is called, the common language runtime (CLR) queues the request and returns immediately to the caller. The target method is called asynchronously on a thread from the thread pool.

How does async method work?

The async keyword turns a method into an async method, which allows you to use the await keyword in its body. When the await keyword is applied, it suspends the calling method and yields control back to its caller until the awaited task is complete.

The async equivalent of Action<T> is Func<T, Task>, so I believe this is what you're looking for:

public async Task<T> DoSomethingAsync<T>(Func<T, Task> resultBody)
    where T : Result, new()
{
  T result = new T();
  await resultBody(result);
  return result;
}
