Run a REST WCF Service with Fiddler or Visual Studio Debug --- Read & Reconstruct XML Data

Question

User764773883 posted

All,

I am attempting to create a service that'll produce XML from HTTP GET. However, when I go to debug the service I receive the error "Failed to add a service. Service metadata may not be accessible." When I attempt the debug off another file and local host becomes active, I use fiddler to see if I can GET from my localhost address with the certain parameters of my service. However, when I do this I get the standard 404 error.

I don't think it is my code (I have created two version so far -- using XmlSerialization and DataContract) and I still receive the error. I am guessing it has to be my Web.config file or the markup on my .svc file.

Here is what I got for Web.config:

<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <services>
      <service name="ShowtimeService.ScheduleService" behaviorConfiguration="ServiceBehavior">
        <!--Service Endpoints-->
        <!--<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />-->
        <endpoint address="" binding="webHttpBinding" contract="ShowtimeService.ISchedule" behaviorConfiguration="REST" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehavior">
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="REST">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>
</configuration>

Here is what I got for my ScheduleService.svc:

<%@ ServiceHost Language="C#" Debug="true" Service="ShowtimeService.Schedule" CodeBehind="ScheduleService.svc.cs" %>

Any help is better than no help. Thanks for your time.

Kushalrdalal,

I have referenced this link. this is a very good walkthrough. I have figured out why I was unable to add my service. Now I am going through debugging one method of my service. Right now, I am having issues getting my service to read an XML file for parsing.

Post some code here how you try to read the xml and where you are getting issues.

Sorry about the late reply Kushalrdalal. For some reason, I am not getting emails about replies.

So I am reading the xml file fine now. Now I have to create my own XML from this XML. Essentially, I am only pulling out data that I need to create a new XML file. 

I am experiencing a weird issue now though.

Here is a snippet of what I am trying to do:

Performance show;
Schedule showsForDay = new Schedule();

IEnumerable<XElement> performancesPerShow = from XElement ppf in show.Descendants("performance") select ppf; //obtain each performance for the selected show
                    foreach (XElement performance in performancesPerShow)//for each performance obtained in the LINQ query above
                    {
                        shows.Add(performance.Attribute("showTime").Value.ToString());
                        roomLocations.Add(Convert.ToInt32(performance.Attribute("roomLocation").Value.ToString()));
                    }
                    showPerformances = new Performance(Convert.ToInt32(film.Attribute("code").Value.ToString()), shows, roomLocations);
                    showsForDay.Add(showPerformances);
}
return showsForDay

All in all, the Schedule class is a List of Performances (aka List<Perfomances>). So, if I leave my code like it is the lists -- shows and roomLocations -- will contain old data from a previous performance. This will create false data within the new XML I have to create. As a result, I tried to use the Clear() method of List after I add the performance object to showsForDay. However, when I do this it clears all of my list data in showsForDay. I have some more ideas that I am going to try but you all may know what mistake I am making.

Thanks,

BB
