Welcome

PPL (Parallel Patterns Library) Power Pack is a Microsoft feature extension package for PPL Tasks in Visual Studio 2012 and Visual Studio 2013 Preview. This power pack will improve C++ async-programming experience by introducing new programming patterns and utilities. It includes several frequently customer requested features as well as some experimental features. We hope that with positive customer feedback we fully support these features in upcoming releases of PPL.

PPL Power Pack is a header only add-on library and requires Visual Studio 2012 or Visual Studio 2013 Preview to be preinstalled. Please note that some features are only supported in Visual Studio 2013 Preview. For more details please refer to Supported platform.

Here are the features included in the PPL Power Pack

  • Ability to composite multiple tasks with different types by using when_all / when_any.
  • Ability to pass local variables though continuations without using global variables.
  • Ability to easily create an async task continuation loop on fly.
  • Ability to run or cancel tasks after a given time.
  • Ability to report and track progress information for tasks. It also enables tasks reading progress information from an IAsyncOperationWithProgress^ object.

Fast evolution

PPL Power Pack will be updated more frequently than Visual Studio, and we love to provide new features and improvements based on your feedback. However, because of the experimental nature, it may:
  1. Introduce breaking changes in future releases.
  2. Be less stable than product quality.
Please take this into consideration if you want to use it in your product.
