Question

I am writing a WCF service, (json REST) and I have it working fine when using the wcftestclient.exe

When I run that test tool it triggers my break points while debugging and everything works as expected.

but, when using a browser to navigate to the the service and method, no break point is triggered. it seems as though the request isnt even getting to the code.

I receieve no errors on when navigating with web browser to the service, it just doesn’t get any data, or trigger the break points.

Apologies if this is a duplicate, I have read and tried many many different configurations found in answers to similar questions, but nothing seems to work.

Many thanks for any help, I’ve posted my code below.

I have setup:
ServiceContract

[OperationContract]
[WebGet(BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
List<Country> GetAllCountries();

The Service CLass:

    public List<Country> GetAllCountries()
    {
        ControlServiceRepository rep = new ControlServiceRepository();
        return rep.GetAllCountries().ToList() ;
    }

and my web config

<system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <services>
      <service name="OmniData" behaviorConfiguration="ServiceConfig">
        <!-- Service Endpoints -->
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:55641/"/>
          </baseAddresses>
        </host>
        <endpoint address="" binding="webHttpBinding" contract="ControlService.IOmniData" behaviorConfiguration="rest" />
      </service>
    </services>
      <behaviors>
        <endpointBehaviors>
          <behavior name="rest">
            <webHttp helpEnabled="true"/>
          </behavior>
        </endpointBehaviors>
        <serviceBehaviors>
          <behavior name="ServiceConfig">
            <serviceMetadata httpGetEnabled="true"/>
            <serviceDebug includeExceptionDetailInFaults="false"/>
          </behavior>
        <behavior>
          <!-- 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="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    <standardEndpoints>
      <webHttpEndpoint>
        <standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="false" defaultOutgoingResponseFormat="Json"/>
      </webHttpEndpoint>
    </standardEndpoints>
  </system.serviceModel>
 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>

I got this working in the end by deleting all the end points in the config and using

RouteTable.Routes.Add(new ServiceRoute("", new WebServiceHostFactory(), typeof(OmniData)));

if anyone else has issues, this is even easier than setting up end points because you can just specify the type of responses and end points within the classes themselves.

so:

Add a global.asax if one does exist and include this:

protected void Application_Start(object sender, EventArgs e)
        {
            RouteTable.Routes.Add(new ServiceRoute("", new WebServiceHostFactory(), typeof(OmniData)));
        }

decorate your Service class with

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

here is mine:

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class OmniData : IOmniData
{
  public Country[] GetAllCountries()
  {
    ControlServiceRepository rep = new ControlServiceRepository();
    return rep.GetAllCountries().ToArray() ;
  }
}

then the interface you setup your endpoing and types using WebGet or WebInvoke

public interface IOmniData
    {
        [OperationContract]
        [WebGet(UriTemplate = "OmniData/GetAllCountries", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)]
        Country[] GetAllCountries();
    }

the UriTemplate is the end point, so to access the method you would use: http://MyService.com/OmniData/GetAllCountries

and finally, web config

<system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
    <standardEndpoints>
      <webHttpEndpoint>
        <standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="false"/>
      </webHttpEndpoint>
    </standardEndpoints>
    <services>
      <service name="OmniData">
        <!-- Service Endpoints -->
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:55641"/>
          </baseAddresses>
        </host>
        <endpoint address="" binding="webHttpBinding" contract="ControlService.IOmniData" behaviorConfiguration="rest" />
      </service>
    </services>
    <behaviors>
      <endpointBehaviors>
        <behavior name="rest">
          <webHttp />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="Default">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

Alot of help from here

but, importantly for what I wanted, json results, you need to make sure:
automaticFormatSelectionEnabled=”false” is in there so it will use the response format specified in the interface. Otherwise you end up with XML instead.

hopefully this helps someone else

And thanks again for fiddler!
