Parallel Tasks in .NET 4.0 (Part II) – Methods that Return value

In one of the previous articles Parallel Tasks in .NET 4.0, we explored a set of new API’s called the "Task Parallel Library (TPL)" which simplifies the process of adding parallelism and concurrency to applications. We used the System.Threading.Tasks.Parallel.Invoke() to call methods that did not return a value. However for methods that return a value, you would need to use the Task(TResult) class which represents an asynchronous operation that can return a value. We will explore how to use this class in this article.
