Client not able to access some methods of WCF Service

Hi,

I have designed a small WCF WebService. While I am trying to access its methods from the client; some are able to access but some are not. I am putting piece of code below:

[System.ServiceModel.ServiceBehaviorAttribute(InstanceContextMode=System.ServiceModel.InstanceContextMode.PerCall, ConcurrencyMode=System.ServiceModel.ConcurrencyMode.Single)]
public class RestuarantService : IRestuarantService
{
public virtual GetRestaurantsResponse GetRestaurants(GetRestaurantsRequest request)
{
throw new System.NotImplementedException();
}

public virtual void AddRestaurant(AddRestaurant request)
{
throw new System.NotImplementedException();
}

public virtual void RateRestaurant(RateRestaurant request)
{
throw new System.NotImplementedException();
}

}

From the above piece of code I am not able to access GetRestaurants() method from client. Couldnt understand the reason for this. Can anyone please help me in this.

Thanks & regards,

Afreen

Re: Client not able to access some methods of WCF Service

Wherever you have GetRestaurantsResponse defined, is the class annotated with a [DataContract] attribute and the properties annotated with a [DataMember] attribute?

For example:

    [DataContract]
    public class PurchaseOrder
    {
        private int poId_value;

        // Apply the DataMemberAttribute to the property.
        [DataMember]
        public int PurchaseOrderId
        {

            get { return poId_value; }
            set { poId_value = value; }
        }
    }

Without that, the call won't work because WCF will not understand the return type.

Hi,

Please make sure that GetRestaurants marked as [OperationContract] attribute and GetRestaurantsRequest & GetRestaurantsResponse

marked as [DataContract] attribute. Meanwhile you can also check your .svc?wsdl file wherther the type GetRestaurants exposed and also

try with re-creating service reference from your client.
