The Parallel Patterns Library (PPL) provides a task-based asynchrony model that can make working with asynchronous APIs much easier for C++ programmers. Asynchronous APIs are pervasive in the "Windows 8" Windows Runtime (WinRT). Potentially long-running operations—like file and network I/O—are typically exposed through some asynchronous pattern.
Get the latest PPL to experiment with writing asynchronous code for "Windows 8" Metro style applications. Don't forget to provide feedback to the PPL team! They want to hear from you, so please write some code and see if you find this comfortable/useful/etc.
See the BUILD sessions on WinRT to get more information about asynchrony in "Windows 8."
