WCF - Sending data to server outside of contract

I have a WCF service with a client application. I have complete control over both the client and server implementation. I have hundreds of methods in the WCF contract which need a piece of information supplied by the client. Instead of modifying hundreds of methods, is there a way I can send specific data from the client with every call to the service, possibly somewhere in the channel?

Maybe when the client is setting up the proxy before making the call, it can store this data somewhere in an internal property of the proxy... the data would then get sent to the server and from within the service method I could inspect the OperationContext or some other piece of memory to get this data back and use it?

Any ideas?

Solution

  • It sounds like you are wanting something like headers like with SOAP webservices. I'm not a WCF expert, but this looks like the WCF equivalent.
