Two keys to this for certain flavors of the ' Service attribute value in the ServiceHost directive could not be found'-problem: (1) If you're working in Silverlight, you should use the Silverlight WCF-Enabled Service, not the non-Silverlight WCF Service; this will update Web.Config for the bindings and allow the type to be visible; (2) Match the class name in the new service to the Service name -- the goal here is to make a wsdl... so that you know the service's functionality is exposed to your Silverlight client and to the Web; it helps to have the service match the class. If you get the names gummed up, you will have to edit the Web.Config in 3 places (serviceBehaviors, services and bindings).

There were so many sincere attempts to help folks with this problem that were not helpful to me that it should be stressed that this write-up is for a Silverlight solution and it may not apply for someone not using Silverlight 3 in a client/Web configuration.

Hope it helps.
