View WCF SOAP Message with fiddler

I have a localhost Client and WCF Webservice and I'm trying to see what the SOAP Message looks like and verify that infact a soap+xml is being used.

I tried using Fiddler and i get weird stuff like this:

                <input type="submit" name="cmdGetCapabilities" value="GetCapabilities" id="cmdGetCapabilities" />
                <script type="text/javascript">
LoadRequest('txtGetCapabilitiesRequest', './xml/oseopRequest_GetCa开发者_StackOverflow社区pabilities.xml')</script>
                <h5>
                    Response</h5>
                <br />
                <textarea name="txtGetCapabilitiesResponse" id="txtGetCapabilitiesResponse" cols="70" rows="10">Hello test response string</textarea>
            |156|hiddenField|__VIEWSTATE|/wEPDwULLTE4NzQ1MTA5MDIPZBYCAgMPZBYCAgMPZBYCZg9kFgICAw8WAh4JaW5uZXJodG1sBRpIZWxsbyB0ZXN0IHJlc3BvbnNlIHN0cmluZ2RkqYOXbJ/FDnErLs5ws2ZmhyRiXwZoUdF7s5KAUS3NgVU=|72|hiddenField|__EVENTVALIDATION|/wEWAwKEj88XAoyqi+0CAoH3wsYJfbp248BhSjkeWuuXYou1JuSHEFMD2NrnszOSKQq7YZg=|0|asyncPostBackControlIDs|||0|postBackControlIDs|||26|updatePanelIDs||tUpdatePanel1,UpdatePanel1|0|childUpdatePanelIDs|||25|panelsToRefreshIDs||UpdatePanel1,UpdatePanel1|2|asyncPostBackTimeout||90|12|formAction||default.aspx|

But fiddler is picking up the client posting back or calling the "click" event and returning data to the browser, there is no session entry that shows the client calling my WCF svc page.

I tried using the TraceViewer which i can see the calls to my web method but no soap envelope.

Anyone know how to view the sending and receiving messages of WCF?

Have you considered switching on Message Logging?
