Sometimes, simple things end up as epic battles. If you try to MSN Search and Google for the nasty “You have create a Service” page for IIS hosted WCF services, you will and up with a lot of pre-release information and noise in the search results. Actually, you might spend days in finding some relevant information.
Yesterday, I was finally pointed to the right place in the MSDN documentation where you can find this specific information:
<serviceDebug httpHelpPageEnabled="Boolean" httpHelpPageUrl="Uri" httpsHelpPageEnabled="Boolean" httpsHelpPageUrl="Uri" includeExceptionDetailInFaults="Boolean" />
With the serviceDebug tag it should be possible to get rid of the page. It is easy to find as long as you know you have to search for the term HTML help page.
