The contract name 'x.y.IService' could not be found in the list of contracts implemented by the service 'z.t.MyService'

I'm working on a very simple WCF service. At the beginning everything was fine, then I moved the service interface in a separated DLL file. Since that I got this error:

The contract name x.y.IService could not be found in the list of contracts implemented by the service z.t.MyService

My config file looks like this:

   <endpointBehaviors>
      <behavior name="webHttpBehavior">
         <enableWebScript />
      </behavior>
   </endpointBehaviors>
</behaviors>
<services>
   <service name="z.t.MyService">
      <endpoint address=""  
                binding="webHttpBinding" 
                behaviorConfig开发者_Go百科uration="webHttpBehavior"
                contract="x.y.IService" />
   </service>
</services>...

and my service looks like this:

using x.y;

namespace z.y
{
    public class MyService : IService
    {

    }
}

Everything else but the service works fine with that namespace. Where am I wrong?

Thanks in advance.

Everything looks fine assuming the z.t.MyService is a typo. This is exactly what we do and everything works for our service.

Edit based on comments: Yes, the interface can be a generic, however you will need to define the type before using it in the service.

You can do the following

public interface IActualService : IService<MyService>

Then you just use IAcutalService as the interface for your service.
