Question

So I am sending entities over WCF. What I would like to do is to have an opportunity to alter the entities in any way I want before they go over. I do not have to do this in the WCF but I don’t see another place to do it, as I want one single place to do it.

Open to suggestions though if anyone has another way to do it 🙂

I have the usual layers of DAL, Domain and Service. They all share a Common too.

I think you are talking about Message Inspectors

A message inspector is an extensibility object that can be used in the
service model’s client runtime and dispatch runtime programmatically
or through configuration and that can inspect and alter messages after
they are received or before they are sent.

This sample implements a basic client and service message validation
mechanism that validates incoming messages against a set of
configurable XML Schema documents. Note that this sample does not
validate messages for each operation. This is an intentional
simplification.

Also take a look into IParameterInspector, here you can handle all input/output parameters in client and server side
