This session will cover .NET parallel programming in the present and future. Starting with a recap of the parallel programming libraries in Framework 4.0, we'll highlight the most effective patterns for levering today's multicore processors - along with some cool tricks and tips. Then we'll take a preview at what's coming in the next .NET Framework with TPL Dataflow. We'll demonstrate how an actor-based model inspired by quantum mechanics takes parallelism and concurrency to the next level, reducing latency and simplifying design through a message-based architecture. We'll also look at how this ties in with the upcoming asynchronous language features, and how to get started with the CTP today.
