How to use IDispatchMessageInspector in a WCF Service?

Question

I am trying to use IDispatchMessageInspector in a WCF service implementation to access custom header values.

Something like:

public class MyService :

On the MSDN page that you linked to there is also a description how an inspector can be inserted and also an example of that. To quote:

Typically, message inspectors are inserted by a service behavior, an endpoint behavior, or a contract behavior. The behavior then adds the message inspector to the DispatchRuntime.MessageInspectors collection.

Later on you have the following examples:

• Implementing custom IDispatchMessageInspector
• Implementing custom IServiceBehavior that adds the inspector to the runtime.
• Configuration of the behavior via .config file.

That should be enough to get you started. Otherwise feel free to ask :)

If you just want to get access to headers from within your service, you could try OperationContext.Current.IncomingMessageHeaders.
