System.Threading.Tasks.Unofficial by: Robert McLaws, Jrmie "Garuma" Laval

**NOTE: Formerly System.Threading.Tasks.** This package is a port of the Mono version of the *complete* Task Parallel Library (not a subset) to .NET 3.5, as well as all Silverlight platforms, including Windows Phone 7.x. This version contains more classes (and is namespace compatible with the BCL) compared to the PortableTPL project. This project supercedes the TaskParallelLibrary.WP7 package, and is licensed under the same licenses as the rest of the Mono framework.
