TPL Dataflow announcement

Link
In .NET 4.5 RC, TPL Dataflow is delivered via NuGet at https://nuget.org/packages/Microsoft.Tpl.Dataflow and is supported everywhere that .NET 4.5 runs, including desktop, server, and .NET for Metro style apps. The simplest way to install the package in Visual Studio is to highlight the target project, select Tools > Library Package Manager > Package Manager Console, and at the prompt enter:
Install-Package Microsoft.Tpl.Dataflow -Pre
The -Pre flag is needed because these are marked as prerelease versions. You can use the GUI Manage NuGet Packages dialog for this task as well, but when searching make sure to select Include Prerelease from the appropriate drop-down list. For details about this release, please refer to the blog post at http://blogs.msdn.com/b/bclteam/archive/2012/05/30/mef-and-tpl-dataflow-nuget-packages-for-net-framework-4-5-rc.aspx. -

"TPL Dataflow" is a new .NET library for building concurrent, parallel, and asynchronous applications. It enables building systems based on dataflow concepts, on in-process message passing, and on asynchronous pipelines. This library, System.Threading.Tasks.Dataflow.dll, is heavily inspired by the Visual C++ Asynchronous Agents Library, by the CCR from Microsoft Robotics, by the Axum language, and more; it’s built on top of a multitude of constructs introduced in .NET 4, internally using types like Task and ConcurrentQueue<T>, in order to provide solutions for buffering and processing data, for building systems that need high-throughput and low-latency processing of data, and for building agent/actor-based systems. TPL Dataflow was also designed to integrate very well with the new language support for tasks, such that you can easily use TPL Dataflow constructs within asynchronous methods, and such that you can harness asynchronous methods within “dataflow blocks.”
You can download a Community Technology Preview release from the TC Labs site on MSDN DevLabs at http://msdn.microsoft.com/en-us/devlabs/gg585582. A previous preview release of the DLL is also available as part of the Microsoft Visual Studio Async CTP, available at http://msdn.com/vstudio/async.
Please use this forum to ask questions about TPL Dataflow, to provide feedback on the library, to let us know about your successes and to let us know about your stumbling blocks. We look forward to hearing from and conversing with you.
