Implementing TAP using compilers

Any method that is attributed with the async keyword (for C#) or Async for (Visual Basic) is called an asynchronous method. The async keyword can be applied to a method, anonymous method, or a Lambda expression, and the language compiler can execute that task asynchronously.

Here is a simple implementation of the TAP method using the compiler approach:

static void Main(string[] args) 
{ 
  var t = ExecuteLongRunningOperationAsync(100000); 
  Console.WriteLine("Called ExecuteLongRunningOperationAsync method,  now waiting for it to complete"); t.Wait(); Console.Read(); } public static async Task<int> ExecuteLongRunningOperationAsync(int millis) { Task t = Task.Factory.StartNew(() => RunLoopAsync(millis)); await t; ...
