How to run WCF service while changing the namespace in WCF Service Application project?

Question

I have added "WCF Service Application" project type to my VS solution(4.0). Now, the default namespace that appears is "Service" and if I run the application (Pointing WCF service application as the startup project) it works fine.

Now I have changed the namespace to XXX.YYY.Service.PartnerPortal as under

namespace XXX.YYY.Service.PartnerPortal
{        
    public class Service1 : IService1
    {
        public string GetData(int value)
        {
            return string.Format("You entered: {0}", value);
        }        
    }
}

As well as the IService1 interface also

namespace XXX.YYY.Service.PartnerPortal
{    
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string GetData(int value);        
    }
}

Also I have changed the default namespace in the project properties

The app.config file is as under

<?xml version="1.0"?>
<configuration>
    <system.web>
        <compilation debug="true" targetFramework="4.0">
        </compilation>
        <pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"/></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">
        </modules>
    </system.webServer>
</configuration>

And while trying to run, the error messageI am receiving is

What wrong I am doing and how to fix it?

Answer 1

Open your svc file, and correct the namespace in the Service attribute value

<%@ ServiceHost Language="C#" Debug="true" Service="XXX.YYY.Service.PartnerPortal.Service1" .....
