This post is part of a series about WCF extensibility points. For a list of all previous posts and planned future ones, go to the index page.

The message inspectors, described in the previous post of this series, allows you complete control over the message going through the WCF stack. They’re very powerful, but you have to know how to deal with the Message object, which is not the most desirable way of programming. If the service model in WCF hides all the messaging framework by allowing us to define our services in terms of strongly-typed operations (i.e., using nice primitive and user defined types), there should be a way of intercepting requests / responses after all the processing to extract those parameters from incoming messages (or before they’re packaged in outgoing messages) is done. The IParameterInspector is exactly that – before and after each call, the inspector gets a chance to inspect the operation inputs, outputs and return value, in the same types as defined by the operation contract, no conversion needed (the only thing needed is a cast, since the parameters are passed as objects).
