Coming from a DCOM world, I'm trying to write a singleton type service that does not necessarily require user interaction via a GUI but needs to be programatically addressable.
This application should be run at startup like a Windows Service (in fact I would prefer a Windows Service but I understand that starting with Vista it is a no-no to have a program interface on a service). Also needs to be reachable in a client/server setup.
Not really a web environment - I'm thinking maybe WCF?
Suggestions anyone? Thanks!
