5.1. Parallelization Overview

Some of the parallelization enhancements might look familiar to a few readers because they were released previously as part of the parallel extensions. .NET 4.0 builds on this work but brings the extensions into the core CLR within mscorlib.dll.

The parallel extensions and enhancements can be divided into five main areas:

• Task Parallel Library (TPL) and Concurrency and Coordination Runtime (CCR)

• Parallel LINQ (PLINQ)

• New debugging and profiling tools

• Coordination data structures

• Parallel Pattern Library (PPL) (C++ only; not covered)
