Hi Jeffrey, I am excited to hear about these features. I think they work great for debugging for sure. And I would use ResumeCallback for copying the thread

So I'm interested in your comment about 'having a change of heart about some things.' I just took your class a month or two ago, and am in the process of

Yes, the TPL offers work-stealing queues but these are only for compute-bound operations and, in fact, only work with the new Task class. The AsyncEnumerator

Wow, great news! In the future, it will be interesting to make some perf test between the current version and the one that will use .NET 4.0 stuff internally!

OK, I fixed all the links in my document but I haven't uploaded the new version yet. Thanks for letting me know about it. MSDN changed a bunch of stuff

While you're at it, the pdf contains a number of broken links to your MSDN articles. Or at least they're broken for me:

When you construct a Singleton, you pass it a delegate that refers to code that returns a T. The Singleton class ensures that a lock is taken around

Singleton and InitalizeOnce

Is there sample code available that shows how to use Wintellect.Threading.Singleton? I'm interested to understand how a generic singleton works -- can't

Excellent! I just made the change. Works great, and code is *much* cleaner -- no more instance variable(s). Thanks

Re: AsyncEnumerator.BeginExecute

Jeffrey Richter (Wintellect LLC) — Mon, 09 Nov 2009 21:22:39 GMT

Yes, as my code in Figure 2 of the article is written, there would be a problem if m_webSiteDataLength is overwritten. To address this, my AsyncEnumerator has

I have designed a class that acts like Figure 2 in your article http://msdn.microsoft.com/en-us/magazine/cc721613.aspx (except I'm working with a Windows Form

Jeffrey Richter (Wintellect LLC) — Sun, 08 Nov 2009 18:46:52 GMT

AsyncEnumerator.BeginExecute

I think I need a better understanding the AsyncCallback parameter of AsyncEnumerator.BeginExecute(). I understand that to be a callback method that the ae will

The exception is being thrown from with9in an EndXxx method. You just have to put the EndXxx method in a try block and then you can catch the SocketException.
