Remember back in the VB6 days when you would set your objects to null when you're done with it? Well, so did someone else here, because that's what I saw.

If there's an error when the service first starts up, the workaround is to introduce a Thread.Sleep before it actually does anything, giving you enough time to attach the debugger. By default, you can't directly run the service from within Visual Studio. If you try, you get the following message: If you look at the code that actually starts the service, you'll see that it's not that different from a console app. By default, it looks something like this:      internal   static   class   Program     {          ///   <summary>          ///  The main entry...
