WCF Interface from another assembly

Question

Hi

I'm still pretty new to WCF, so maybe this is a stupid question.

I have a WCF service and was wondering if it were possible to reference different DLL's with service contracts in them and make them accessible through the same service?

So I would have one dll with something like this in it:
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
  public partial class MyTestClass : IMyTestClass
  {
 
  public string _TestSalesOptions()
  {
  return "SalesOpstion says Halo!";
  }
  }

[ServiceContract]
  public interface IMyTestClass
  {
  [OperationContract]
  string _TestSalesOptions();
  }


Now... would I be able to reference this dll in my main service and add a endpoint??
I've spend the better part of the morning googling and I haven't found any results to what I'm trying to do. Maybe it can't be done? Maybe we should rather create separate small services?

 

Answer 1

Can you share the test project which you are working on. I can fix it and give it for you.

Answer 2

I can't get it to work. It keeps telling me that it can't find my contract. I'm thinking the service does not know to look for IMyTestClass in MyTest.dll. Can I tell it in what dll to look for the code?? If so how?

Answer 3

It should work. Give it a try. Let me know if you are facing any issues.

Answer 4

What if I want to add more than one dll, but I make the namespace the same? I'm going to give it a try.

Answer 5

You dont have to do that. You have to specify the proper namespace of the interfaces project in the endpoint like

 <endpoint address="" binding="basicHttpBinding"  name="BasicHttpBinding_IServiceName"   contract="<Interface Namespace>.InterfaceName">


Keynote is the projects namespace should be mentioned properly.

Even in the .svc file you need to mention proper namespace

<%@ ServiceHost Language="C#" Debug="true" Service="<NameSpace of service methods>.Name of service method class" CodeBehind="path of service method class file" %>

Answer 6

Can you elaborate a little more? What do I need to do in the config file? I'm assuming just adding an extra endpoint won't do it?

Answer 7

It can be done. You can event put data contracts, operation contracts in separate project. You have to configure the web.config properly.
