How to: Create Threads
The BackgroundWorker component replaces and adds functionality to the System.Threading namespace; however, the System.Threading namespace is retained for both backward compatibility and future use, if you choose. For more information, see BackgroundWorker Component Overview.
With the .NET Framework, you can create multithreaded applications quickly and easily by providing an object-oriented threading model. Creating a new thread is as easy as declaring it and supplying it with a delegate to the method where the thread is to start. When you are ready to begin execution on the thread, call the Thread.Start method. There are special considerations involved when working with multiple threads of execution. For information about the techniques involved in working with multiple threads, see Thread-Safe Components.
