Next Step: Summary
Summary In this lab, you have worked with the Parallel Extensions library to understand its features to help you work with parallel tasks in a simple, controllable fashion. You’ve learned how to use Parallel Extensions classes like Parallel and Task to manage units of work. You’ve dealt with Parallel Extensions features like Wait(), WaitAll(), IsComplete(), and ContinueWith() to control the flow of your execution. You’ve also worked through examples of using PLINQ to deal with parallelizing queries. This lab has given you a solid introduction to the Parallel Extensions library and its power and benefits.
