Adam,
I believe the problem relates to the open-generic registration. The Wcf
Facility waits for the service to be in the ready state before it opens the
host. In this case, the container shows the ServiceGenericDependency component
as waiting for the IDecorator dependency. It would be nice for the container
to handle this properly. I have seen this before and added an option to open
the service host eagerly. This will not wait for the component to be reported
as valid before opening the host. In your example, it resolved the issue
var wcfFacility=XXXX
wcfFacility.Services.OpenServiceHostsEagerly = true;
cheers,
craig
