title: Unity RegisterInstance on runtime (Not from Config file)
body: <p>I have a wcf service which provide a main configuration to all the other services in the system.</p>
  
  <p>According to the configuration, I would like to create an instance (RegisterInstance\Type) at runtime.</p>
  
  <p>I found only samples for how to do it by a configuration file. </p>
  
  <p>I want to recieve the type from my configuration service.
  All the types which I can get from the service are inherit from the same interface.</p>
  
  <p>How can I do it without configuration file? </p>
  
  <p>Thanks</p>
