Without Castle Windsor I would write:
var channelFactory = new ChannelFactory<ICredentialService>("Default");
ICredentialService credentialService = channelFactory.CreateChannel();
How can I register a Wcf Service contract with the Castle Windsor API?
Add the Castle Windsor WCF integration facility Nuget package to your project
Add the WcfFacility
to your container:
container.AddFacility<WcfFacility>();
Then, tell the container to provide a WCF client when you have a dependency on your service interface:
container.Register(
Component.For<ICredentialService>()
.AsWcfClient(WcfEndpoint.FromEndpoint("EndpointName")));
It will then use the named endpoint in your .config to retrieve the settings for the endpoint.
Whenever a class resolved from the container has a constructor dependency on ICredentialService
the container will inject a WCF client.
