Reusable Timer Service

you can have a service instance per timer configuration. The service reads its configuration from a file or gets it from a Replace message on starup(its state type is the timer definition class a mention above). Other services start their own private instance, with custom parameters.

Alternatively you can have a single service, that keeps a list of timer configurations (some simple class you define that has the a friendly timer name, timer interval, repeat count etc). Other services can send Insert messages to add a timer, Delete messages to remove one, etc.

For notifications, service can send Subscribe messages ( a custom SubscribeRequest that derives from our SubscribeRequestType) that specifies the name of the timer you want to subscribe.

The timer service cam then use Submit to submit notification tot he subscription manager, using the timer name as the "key" (so only services subscribed to this timer get the notification).
