title: Specify a Singleton service in a WCF self hosted service
body: <p>I am writing an application that exposes a service via WCF. The service is self-hosted (console app) and needs to use a Singleton instance. I am trying to figure out how to specify singleton in the service configuration <em>without</em> using attributes on the service implementation. Is it possible to specify singleton in code without an attribute?</p>
  
  <p>Thanks,
  Erick</p>
