Registering a WcfClient in the container when the URI not yet known

Question

At the time I am registering a new WCF endpoint I do not know what the URI is...

public void Install(IWindsorContainer container, IConfigurationStore store)
{
   var defaultClientModel = new DefaultClientModel
   {
     Endpoint = WcfEndpoint
       .ForContract<IMyService>()
       .BoundTo(new WSHttpBinding(SecurityMode.None))
       .At(  URI??? )
   };

   container.Register(WcfClient.ForChannels(defaultClientModel));
}

Is there some way I can retrieve the URI from the container at the time the IMyService instance is requested (this is when it is known)?

Is there a factory method/dynamic parameter sort of thing that could be used?

Why don't you know what the URI is? Where are you getting your URI from? — Aran Mulholland, Oct 10 '12 at 06:05
The service that knows the URI is in the container. I don't want to reference the container in a service-locator fashion. Janco's is what I was looking for! — KevinT, Oct 15 '12 at 14:02

It looks like you're able to do so using the following syntax in Windsor 3.1:

public void Install(IWindsorContainer container, IConfigurationStore store)
{
container.Register(
    Component.For<IMyService>()
    .AsWcfClient()
    .DependsOn((k, d) =>
        d["EndPoint"] = WcfEndpoint.BoundTo(new WSHttpBinding(SecurityMode.None)).At( URI??? )));
}

Windsor will attempt to resolve the endpoint using the given dynamic resolution delegate at the point when an IMyService is first resolved.

Thanks a lot! I wish I could give you +200 too :) – Mike Dec 06 '12 at 22:24 — Mike, Dec 06 '12 at 22:24

I think you want to use the UsingFactoryMethod to create your services.

I would register a custom UriResolver with the container
Resolve an instance of the said UriResolver in the factory method (which doesn't get called until the service needs to be resolved)
Create the service in the factory method
Search through the Castle Windsor doco and swear a lot.
