Question

I have created a new wcf4 web application and added a new wcf service.
I created a subfolder and moved the service created into the subfolder.

e.g.

ROOT
ROOT/Business/V1/BusinessV1.svc

I have deployed the service onto my IIS7 enviroment however I keep getting this error

The type
‘MyNameSpace.WebWCF.Business.V1’,
provided as the Service attribute
value in the ServiceHost directive, or
provided in the configuration element
system.serviceModel/serviceHostingEnvironment/serviceActivations
could not be found.

My service file looks like this

<%@ ServiceHost Language="C#" Debug="true" 
    Service="MyNameSpace.WebWCF.BusinessV1" CodeBehind="BusinessV1.svc.cs" %>

The code behind looks like

namespace MyNameSpace.WebWCF
{
  public class BusinessV1 : IBusinessV1
  {
  }
}

My contract looks like

namespace MyNameSpace.WebWCF
{
   [ServiceContract]
   public interface IBusinessV1
} 

Finally my web.config

<system.serviceModel>
   <services>
      <service name="MyNameSpace.WebWCF.Business_v1">
         <endpoint 
             address="http://mydomain.com/Business/v1/BusinessV1.svc" 
             binding="basicHttpBinding" 
             bindingConfiguration="" 
             contract="MyNameSpace.WebWCF/IBusinessV1" 
             listenUri="/" isSystemEndpoint="true" />
      </service>
   </services>
   <behaviors>
      <serviceBehaviors>
         <behavior name="">
            <serviceMetadata httpGetEnabled="true" />
            <serviceDebug includeExceptionDetailInFaults="false" />
         </behavior>
      </serviceBehaviors>
   </behaviors>
   <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>

Can someone please help me with what I am doing wrong? its driving me crazy.

Answer 1

Well one thing is: your service name isn’t consistent.

In your service implementation class, you have:

namespace MyNameSpace.WebWCF
{
  public class BusinessV1

and in your *.svc file, you have the same qualified name:

Service="MyNameSpace.WebWCF.BusinessV1"

but in your web.config, you use:

<service name="MyNameSpace.WebWCF.Business_v1">

Your service implementation is the one that defines the service name – fully qualified with the namespace: MyNameSpace.WebWCF.BusinessV1

So you need to use this fully qualified name – and exactly that – in your *.svc file (OK!) and your web.config:

<service name="MyNameSpace.WebWCF.BusinessV1">

Use MyNameSpace.WebWCF.BusinessV1 insstead of MyNameSpace.WebWCF.Business_v1.

If that name doesn’t match, the WCF runtime won’t find the config you’ve specified and will fall back to system defaults
