Fx 4.0 Parallel Extension

There are three primitives for Parallelism in Fx 4.0: Task, Paralle.For and PLINQ.

Task t1= new Task(delegate)
t1.Start()
t1.Wait()

Parallel.For(0,100, i=> { });  // lampta expression

IEnumerable nums = Enumerable.Range(0,10000);
IEnumeralbe results= from n in nums.AsParallel()
                           where testcondition(n)
                           select n
