C# - Can't find usage of method when inherited and used through an interface implemented by the subclass

Question

I'm using VisualStudio 2008 and 2010, both with ReSharper, and when I try to lookup for usages of a given method I get no results, despite the method being inherited and then called through an interface. What's wrong? Is that a VS/ReSharper bug? See the example below:

using System;
namespace UsageNotFound
{
   interface MyInterface
   {
       void Hello();
   }

   class SuperClass
   {
       public void Hello() //NOTE: VS 2008/2010 (with resharper)
seems unable to find usages on this!!!
       {
           Console.WriteLine("Hi!");
       }
   }

   class SubClass : SuperClass, MyInterface
   {
       public static MyInterface GetInstance()
       {
           return new SubClass();
       }
   }

   class Program
   {
       static void Main(string[] args)
       {
           SubClass.GetInstance().Hello();
       }
   }
}

Thanks, Fabrizio
