Whether you are developing for computers with one processor or several, you want your application to provide the most responsive interaction with the user, even if the application is currently doing other work. Using multiple threads of execution is one of the most powerful ways to keep your application responsive to the user and at the same time make use of the processor in between or even during user events. While this section introduces the basic concepts of threading, it focuses on managed threading concepts and using managed threading.
Starting with the .NET Framework version 4, multithreaded programming is greatly simplified with the System.Threading.Tasks.Parallel and System.Threading.Tasks.Task classes, Parallel LINQ (PLINQ), new concurrent collection classes in the System.Collections.Concurrent namespace, and a new programming model that is based on the concept of tasks rather than threads. For more information, see Parallel Programming in the .NET Framework.

Provides an overview of managed threading and discusses when to use multiple threads.
Using Threads and Threading
Explains how to create, start, pause, resume, and abort threads.
Managed Threading Best Practices
Discusses levels of synchronization, how to avoid deadlocks and race conditions, single-processor and multiprocessor computers, and other threading issues.
Threading Objects and Features
