A Debuggable Windows Service in Csharp

This is a great example of a windows service. I use it in a app that reads email from pop, and updates a database/webapp written in SilverLight for the FrontEnd.

One note, this uses a Timer Approach to initiate the check. I found unless I put a lock around the worker class,I would see the timer fire again, and I get get a breakpoint in another "thread", while debugging the first. The lock fixed the issue. But take note if you using this or something similar.
