Hello, I am writing a prototype application using WCF, which has proved to be a REAL challenge.
Basically I have worked through my c# code, and that is looking fine, but I keep having issues with the configuration (masses of errors I have no hope in debugging).
Below is my third attempt (cut right back to the barest essentials), now when I run the service a message comes up "WCF Service Host cannot find any service metadata. This may cause the client application to run improperly. Please check that metadata is enabled. Do you want to exit?"
NOTE: the app.config file is generated so I am not sure what can be wrong with it... (I have tried remove all the namespaces just incase they were wrong (as I added them later), no effect.
