WCF implementing without using interface

Hi Ashman786,

In General it is a bad idea to implement Services without Interfaces, cause the Interface represents the Service contract. Anyway I don't see any reason why you can't do "both".

Look at this example code "structure".

You can work with inheritance - also with Interfaces.

So you have:

a Interface for common Service operations like this:

[ServiceContract]
public interface ICommonServiceMethods
{
    [OperationContract]
    string WriteLog(string strMessage);
}

a specific Service Interface inherited from the common operations Interface like this:

[ServiceContract]
public interface IService1 : ICommonServiceMethods
{
    [OperationContract]
    string GetData(int value);
}

You can implement your common Service operations in a base class (could be abstract)

public class BaseService : ICommonServiceMethods
 {
     public string WriteLog(string strMessage)
     {
         return strMessage; //dummy
     }
 }

And then just derive your specific Service instance from the base class while implementing the specific Service.

public class Service1 : BaseService, IService1
{
    public string GetData(int value) { return value.ToString(); /* dummy */}
}

So no need to think about omitting "Interfaces" - although technically you could...

I hope this helps?

Kind regards Johannes
