And I've never really liked seeing that, so in practice I tend to 
implement my Factory like this:

public static class Factory {
   private static IFactory Instance;
   public static void Configure( IFactory instance ) {
     Instance = instance;
   }
   public IMessageClient CreateMessageClient() {
     return Instance.CreateMessageClient();
   }
}

Which then allows me to simplify my client code a tad, so it looks like 
this:

   IMessageClient mc = Factory.CreateMessageClient();
