title: Using .NET BackgroundWorker class in console app
body: <p>I am relatively new to .NET programming and multithreading in general, and was wondering if it is ok to use .NET provided BackgroundWorker to spawn off worker threads to do some work in a console application? From the various documentation online, I see that intent for this class is more for UI oriented applications, where you want to do some work in background, but keep the UI responsive, and report progress, cancelling processing if needed etc. </p>
  
  <p>In my case, basically I have a controller class where I want to spawn off multiple worker threads to do some processing (limiting the max number of worker threads spawned using a semaphore). Then I want my controller class to block until all the threads have completed processing. So after I start a worker thread to do some work, I want the thread to be able to notify the controller thread when processing is complete. I see that I can use the background worker class, and handle events DoWork and RunWorkerCompleted to accomplish this, however was wondering if this is good idea? Are there better ways to achieve this?</p>
