Error in WCF Error “ does not implement interface member “ in Silverlight and ASP.Net Application

In IServiceIncident.cs

[ServiceContract]

    public interface IServiceIncident

    {

        [OperationContract]

        List<clsApplicationsList> mFnGetApplicationsList();

        [OperationContract]

        List<clsProgramList> mFnGetProgramsList();

    }

And have corresponding classes defined correctly as…

  [DataContract]

    public class clsApplicationsList

    {

       public string _AppName = "";

        [DataMember]

        public string Prp_AppName

        {

            get

            {

                return _AppName;

            }

            set

            {

                _AppName = value;

            }

        }

In IServiceIncident.svc.cs

  public class ServiceIncident : IServiceIncident

    {

public List<clsApplicationsList> mFnGetApplicationsList()

        {

            try

            {}

  public List<clsProgramList> mFnGetProgramList()

        {

            }

__------------------------------------------

Here I am getting error in svc.cs file as "Error       1      ...Web.ServiceIncident' does not implement interface member '...Web.IServiceIncident.mFnGetProgramsList()'      ...Web\ServiceIncident.svc.cs     13       18     ...Web"

Any suggestion why this is happening…

Please guide.

Thanks
