.net multithreaded application

Question

I have a multi-core processor, but the .net application I wrote uses only one of the cores. how can I get it to use more than one core when this option is available.

Answer 1

This does not happen for free. Using multiple cores requires multiple threads. You will need to explicitly add thread support to your program in order to use multiple cores at the same time.

Here's a great article exploring how you can use multiple managed-code kernels using parallel library tasks (also known as parallel wireframe extensions ).

multitrheading - ThreadPool.

ThreadPool MSDN:

using System;
using System.Threading;
public class Example {
    public static void Main() {

        // Queue the task.
        ThreadPool.QueueUserWorkItem(new WaitCallback(ThreadProc));

        Thread.Sleep(1000);

        Console.WriteLine("Main thread exits.");
    }

    // This thread procedure performs the task. 
    static void ThreadProc(Object stateInfo) {

        // No state object was passed to QueueUserWorkItem, so  
        // stateInfo is null.
        Console.WriteLine("Hello from the thread pool.");
    }
}
