[SOLVED] WCF singleton service with multiple endpoints?

WCF singleton service with multiple endpoints?

I have a singleton wcf service (InstanceContextMode.Single) i.e MyService with multiple endpoints namely netmsmq and http. The call to netmsmq works fine but when I call it as :

Binding bin = new BasicHttpBinding();
            EndpointAddress end = new EndpointAddress("http://localhost/WcfService1/MyService.svc");
            var obje = new ChannelFactory<IMyService>(bin, end);
            obje.Open();
            var factory = obje.CreateChannel();

            factory.MethodCall(this) ;  //this is ref of MyService1 obj
            obje.Close();

in the ctor of Myservice1 I get a not Serializable exception at the line:

factory.MethodCall(this);

After this I added the [Serializable] and [KnownType(typeof(MyService1))] attributes on MyService1 but now I get a timeout exception If I call MethodCall method.

EDIT: MethodCall method signature is as follows in MyService:

public void MethodCall(IMyService1 obj){}

where MyService1 implements IService.

EDIT 2: Turns out that the http call is trying to hit the address of the netmsmq. I am doing:

 Binding binding = new BasicHttpBinding();
                Uri via = new Uri("http://localhost/WcfService1/MyService.svc");
                 my_host.AddServiceEndpoint(type, binding, "",via);

whereas for netmsmq I am doing:

var contractName = serviceContract + serviceType.Name; 

nbinding.CustomDeadLetterQueue = new Uri(customDlq);
my_host.AddServiceEndpoint(contractName, nbinding, "net.msmq://localhost/private/MyService.svc");

I am using service activation in web.config and I have set multipleSiteBindingsEnabled="true" in service hosting environment. The error that I get is that :

"The HTTP request to 'http://localhost/WcfService1/MyService.svc' has exceeded the allotted timeout of 00:00:59.9940000. The time allotted to this operation may have been a portion of a longer timeout."

EDIT 3: The wsdl location for http are shown as:

http://localhost/WcfService1/MyService.svc

and for msmq as:

net.msmq://localhost/private/WcfService1/MyService.svc

The contracts are all [OperationContract (IsOneWay = true)]

Both services are hosted on IIS and are part of a single project. I was thinking that maybe I cannot use multiple endpoints of a singleton service. Is this the reason? I have been at it for 2 days thought fresh pair of eyes might do the trick. Any help would be appreciated. I can post the stack trace if required.

Solution

Yes, a wcf singleton service can have multiple endpoints.

The problem was solved by using [ServiceKnownType(typeof(MyService1))] over the method declaration in IMyService interface. Like,

[ServiceKnownType(typeof(MyService1))]
public void MethodCall(IMyService1 obj);

It was a serialization issue.
