Managed Threading

.NET Framework 4.5

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.

Note
Starting with the .NET Framework 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.
