Hi,

i am new here and thats my first entry in this forum, i hope somebody can help me with this hopefully easy question? I am trying to implement a base WCF Service from which my sub services should inherit.

My Base Service looks like this:

Class: BaseService.cs
  [ServiceContract]
  public class BaseService
  {
      [OperationContract]
      public DateTime GetDate()
      {
          return DateTime.Now;
      }
  }

Here is my sub Service whicht should inherit all Methods from BaseService.

[ServiceContract]
public class TestService:BaseService
{
    [OperationContract]
    public string SayHello()
    {
        return "Hello";
    }
}

When i try to host my TestService with ServiceHost like this:

ServiceHost _host;
_host = new ServiceHost(typeof(TestService.TestService));
_host.Open();

i get an exception that says something like: the service inheritance can only
be between interface types.
So here is my question: Is there a possiblity to inherit from a Base Service Class
to provide base functionality like getdate() or something like this, or is this absolutly impossible.

Best Regards
Manuel
