Logging SOAP requests and responses

Question

I have added a service reference to my application, with the appropriate proxy classes subsequently being generated.

In my code, I make use of these proxy classes to generate my service calls and to parse the results.

Because .Net takes care of the binding of the HTTP/HTTPS requests and responses, I am unable to view the exact SOAP requests that gets generated by my system.

How can I log the RAW http requests and responses that gets generated by the system, specifically by using Trace.Log, without having to use Fiddler or Wireshark or any other reverse proxy?

UPDATE

It is worth mentioning the following facts as well:

• I am using Visual Studio Professional 2013
• The service I am consuming is a JAX-WS service hosted and owned by a third party. It is out of my control.
• I am calling the service from a class library, which gets invoked from an ASP.Net MVC application (hosted on IIS7.5)
• .Net Framework 4.5

Have a look at implementing the IClientMessageInspector interface, it exposes two methods

AfterReceiveReply Enables inspection or modification of a message after a reply message is received but prior to passing it back to the client application.

BeforeSendRequest Enables inspection or modification of a message before a request message is sent to a service.

Here's a blog post that describes an implementation that reads the message in to raw xml, hopefully you'll be able to alter that to suit your needs http://westdiscgolf.blogspot.ie/2012/09/debugging-wcf-messages-before.html
