Need advice about using on the use of technology (WCF, Web services, etc..)

I have an WPF application. The p开发者_JS百科roblem: need program(daemon, service) that send signals by network to my wpf application and fires some events in real time. Need recomendations how to write this service.

I would recommend looking into WCF.

This would allow you to use a variety of transport mechanisms, and is really the preferred IPC technology for .NET at this point. It really should replace remoting for any new development.
