I have upgraded to 2.5b2, and have gotten a wee bit further, but still no cigar.
The service host can now be created, however, it appears that not all my
endpoints are being created correctly - specifically the IMetaDataExchange one.
Client Code:
FindResponse mexResponse = Discovery.Find(new
FindCriteria(typeof(IMetadataExchange)));
if (mexResponse.Endpoints.Count > 0)
{
if (null == endpointMetadata)
{
CustomBinding binding = new CustomBinding(new
HttpTransportBindingElement());
MetadataExchangeClient mexClient = new
MetadataExchangeClient(binding);
MetadataSet metadata =
mexClient.GetMetadata(mexResponse.Endpoints[0].Address); // the address will be
'http://localhost:81/MEX'
MetadataImporter importer = new WsdlImporter(metadata);
endpointMetadata = importer.ImportAllEndpoints();
}
}
The call to 'GetMetadata' fails, with
$exception {"Metadata contains a reference that cannot be
resolved: 'http://localhost:81/MEX'."} System.Exception
{System.InvalidOperationException}
Because, on the server, Windsor fails to construct the MetadatExchange endpoint
({"The type argument passed to the generic ChannelFactory class must be an
interface type."}) - it is attempting to create a ChannelFactory with my
concrete service type as the generic argument... which obviously isnt possible
because the argument needs to be an interface type.
Is this more obvious?

Subject: WcfFacility does not appear to be compatible with DiscoveryEndpoint
Im not sure how this is going wrong, but I have configured a Windsor
component in my app.config, and a WCF Service. This service has an HTTP
endpoint, and a MEX http endpoint, both of which are advertised via an
HTTP 'discovery endpoint' (not UDP).
Note: My WCF config works without Windsor involved (using a simple
ServiceHost).
The config is LIKE this (pseudo)
<service name="MyService"
behaviorConfiguration="RemoteDiscoveryBehavior">
<endpoint name="customerClient" address=" IMyService"
binding="wsHttpBinding"
bindingConfiguration="wsHttpBindingInsecure"
contract="IMyService"/>
<!-- this is the endpoint address that must be configured in the
ServiceRouter -->
<endpoint name="httpDiscoveryEpt"
kind="discoveryEndpoint"
bindingConfiguration="wsDualHttpBindingInsecure"
binding="wsDualHttpBinding"
address="Discovery"/>
<!-- this is used by the Router to extract the binding
information -->
<endpoint address="MEX" binding="mexHttpBinding"
contract="IMetadataExchange" />
</service>
My server code then looks like this:
var container = new WindsorContainer(new
Castle.Windsor.Configuration.Interpreters.XmlInterpreter());
DefaultServiceHostFactory factory = new
DefaultServiceHostFactory(container.Kernel);
var gatewayHost = factory.CreateServiceHost("MyService", new Uri[] { new
Uri("http://localhost:81/";) });
gatewayHost.Open();
The MyService component is instantiated by Windsor as soon as the
service-host is created, but when the client attempts to perform a
"Find()" to get the service information for the published endpoints, the
client gets this error:
{An ExceptionDetail, likely created by
IncludeExceptionDetailInFaults=true, whose value is:
System.Reflection.TargetInvocationException: Exception has been thrown
