I have had that error before for ServiceModel framework 3.5, and I checked my host's config file. I found it was my cut-and-paste error. My service was pointing to an old non-existing service than the one I am using. It starts working again after I corrected these lines like below:

Note that MyService has to be the name of your contract class in ServiceModel 3.5 BUT IT IS IMyService contract interface in Framework 4.0 -->

namespace InUse {
[ServiceContract]
public interface IMyService 
{
    [WebGet(UriTemplate = "/GetList/{PATTERN}",
        RequestFormat = WebMessageFormat.Json,
        ResponseFormat = WebMessageFormat.Json)]
    [OperationContract]
    List GetIDListByPattern(string PATTERN);

}

[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]    
public class MyService : IMyService
{        
    List MySample = (new _PointRT()).Sample().Select(r=>r._pointXID).ToList();

    public List GetIDListByPattern(string PATTERN) {
        return MySample.Where(x => x.Contains(PATTERN)).ToList();
    }
}
