There are 3 types of timers in .NET:
* System.Windows.Forms.Timer: UI timer. Using only one thread, events
received in the UI thread.
* System.Timers.Timer: worker ("server based") multithread timer. Events
received in a separate thread.
* System.Threading.Timer: lightweight worker ("server based")
multithread timer. Events received in a separate thread.http://www.fawcette.com/vsm/2002_11/online/hottips/falossi/default_pf.asp http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbconServerBasedTimers.asp I'm trying to implement System.Timers namespace in System.dll assembly. I think the simplest solution is to spawn a secondary thread (System.Threading.Thread) doing a (Sleep/Notify Elapsed) loop. What do you think about this early implementation? Somebody could explain more clearly the differences between Threading.Timer and Timers.Timer? Best regards Gustavo. > > 2. I'm interested in implement the System.Timers namespace.
