Question

Ufuk Hacıoğulları wrote a nice WCF helper class called WcfClientBase. However I’ve had some difficulty in implementing it.

I defined my class as follows:

public class ModelsBaseClass : ServiceClientBase<MemberServiceClient>
{...

And attempting to use the helper class in the following method that returns a complex object through Entity Framework:

    public static MyProject.DAL.Primary.Models.sq_newsfeed_GetProfileByID_Result GetAllProfileDetails(int profileID)
    {
        try
        {
            using (memberServiceClient = new MemberServiceClient())                                // connect to the data service
            {
                return memberServiceClient.GetAllProfileDetailsByID(profileID);
            }
        }
        catch (Exception ex)
        {
            ErrorLogging.Instance.Fatal(ex);
            return null;
        }
    }

Following the examples here, I am unable to access the class’ methods even though this is a derived class, and the protected access modifier should allow access – right?

Basically I cannot access the PerformServiceOperation or TryPerformServiceOperation methods in my model base class.

Did you notice your method is static? That’s the reason you cannot access instance members of the parent class.
