title: Unhandled exceptions in BackgroundWorker
body: <p>My WinForms app uses a number of <a href="http://msdn.microsoft.com/en-us/library/system.componentmodel.backgroundworker.aspx" rel="noreferrer">BackgroundWorker</a> objects to retrieve information from a database. I'm using BackgroundWorker because it allows the UI to remain unblocked during long-running database queries and it simplifies the threading model for me.</p>
  
  <p>I'm getting occasional DatabaseExceptions in some of these background threads, and I have witnessed at least one of these exceptions in a worker thread while debugging.  I'm fairly confident these exceptions are timeouts which I suppose its reasonable to expect from time to time.</p>
  
  <p>My question is about what happens when an unhandled exception occurs in one of these background worker threads.</p>
  
  <p>I don't think I can catch an exception in another thread, but can I expect my WorkerCompleted method to be executed?  Is there any property or method of the BackgroundWorker I can interrogate for exceptions?</p>
