WCF Encryption solution for App.config viewable to a client?

Question

I have a desktop application which contains an App.config (program.exe.config at release) with clearly visible elements which define my WCF endpoints and WCF implementation.

Answer 1

I would ideally like to hide this from the users eyes, from simple hacking, view and change.

You really can't protect against this, because anyone who wants to figure out what it's doing just sets a breakpoint on the WCF Endpoint class constructor then hits "go". No amount of obfuscation will help you there.
