I have a server application that spins up and monitors about 8 separate processes that gather data from different systems. The server app then runs some calculations over the aggregated data and stores it in a db. Simple stuff.

I now have a requirement to modify the process so that it no longer saves data to the db but rather exposes it directly to clients via WCF.

That's cool, I've used WCF a fair bit but I'm struggling a little with it for some reason.

Basically my plan is to HOST the WCF service in my application and have calls redirect into the internals of my existing application but I can figure out how to do that without getting the WCF class to encapsulate the existing app.

I want the service to inside my current app, not become it.

Any suggestions?
