Service endpoint binding not using the HTTP protocol

If you are invoking a WCF service and if you are getting the error

"This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details."

Then, most probably you have a problem with enums exposed via WCF. [Even otherwise, this post will be useful to you].

Either case, SvcTraceViewer is your life saver. It helps trace the internal method invocations, plumbing etc in the WCF calls.

Steps to run traceviewer:
1) Configure the WCF to enable trace
2) Run the SvcTraceViewer
3) Open the trace log per the settings in your WCF config file
4) Look for errors. Mostly highlighted in red color.
Info for the above steps available here in the microsoft site.
5) You are not done yet. If it's caused due to enums(as in my case), you must read this blog post that explains the deeper issue underneath using enums in WCF.
