//simple parallel function call
Parallel.Invoke(() => somefunc1(), () => somefunc2());

//parallel foreach with two lists
new List<List> tasks = new List<List>()

//explicit object oriented
   // Create a task and supply a user delegate by using a lambda expression. 
        Task taskA = new Task( () => Console.WriteLine("Hello from taskA."));
        // Start the task.
        // Output a message from the calling thread.
