WCF Service Application template throws error when debugging

Question

I trying to use VS2010 WCF Service Application template to create a new WCF service. After editing the default service contract and updating the implementation of this this contract I tried to run the service from within VS (F5).

The WCF Test Client starts and throws and error while trying to add my service.

Failed to add a service. Service metadata may not be accessible. Make sure your service is running and exposing metadata.

I have not made and changes to the web.config. I am having the same problem posted here.

However, unlike the other posting, my service contract is an interface. Can someone tell me what I am doing wrong?

Thanks!

CheckIn.svc

using System;
using System.IO;

namespace org.myorg.pkggateway
{

    public class PackageCheckIn : IPackageCheckIn
    {
        public bool CheckIn(int value)
        {
            try
            {
                StreamWriter sw = new StreamWriter("test.txt", true);
                sw.WriteLine(value.ToString());
                sw.Close();
            }
            catch(Exception e)
            {
                return false;
            }
            return true;
        }
    }
}

IPackageCheckIn.cs:

using System.Runtime.Serialization;
using System.ServiceModel;

namespace org.myorg.pkggateway {

    [ServiceContract]
    public interface IPackageCheckIn
    {
        [OperationContract]
        bool CheckIn(int value);
    }


   }

Web.config (unchanged from autogen):

    <?xml version="1.0"?>
<configuration>

  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>    
    <behaviors>
      <serviceBehaviors>
        <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" />
  </system.serviceModel>
 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

</configuration>

update

It seems that when I renamed the default .svc file that the template creates refactor did not rename this file everywhere. There must be a reference to it somewhere else. However when I search my entire solution for use of "Service1.svc" it does not exist anywhere. Does anyone know how to clean this up? I even did a search on the file system for a file containing this filename and came up with nothing. I cannot find where VS is still referencing this .svc file. Anyone have this problem?

I have deleted the service altogether and created a new one and the problem still persists.

update

When I run my solution the WCF test client fails to load the deleted service. However the one that does exist works fine. I guess I just have to ignore the fact that I cannot get the test client to "forget" about this service.

What happens if you browse to the .svc file in your application? — carlosfigueira

I don't see any endpoints declared in your web config. At what address do you expose the service? Do you use the development server or IIS? — Pencho Ilchev

@Pencho - if @Nick is using WCF 4.0, he doesn't need to declare endpoints; the default ones will be used. — Tim

Since no endpoints are defined, the "default endpoints" are created - at the base address of the service (i.e., the address to the .svc file). The first thing to try should be to browse to the .svc file itself - if there is a compilation error or some deployment error, it should be shown at that point. — carlosfigueira

@carlosfigueira This is a .net 4.0 application. Since I cannot run this application in VS I don't understand how I might browser to the svc file — Nick

Given that you had a problem with the .svc file, one possible solution is to recreate that file. On VS, create a new text file, rename it to YourServiceName.svc, and add the following content:

<% @ServiceHost Service="org.myorg.pkggateway.PackageCheckIn" Language="C#" debug="true" %>

Then try browsing to the .svc file (or using the WCF Test Client to open the URL of the .svc file).

Yes.. the svc file exists. The problem is the server continues to look for a service called, Service1.svc. I cannot find any reference to this service anywhere in my solution.

Where is the server looking for Service1.svc? When you try to build your app, browse to it, or something else?

You need to go to the properties of the Project and navigate to the Web tab. Then update the Specific Page to the renamed service.
