So you're not really defining it twice; you're defining it once and then defining a delegate with a matching signature in the interface,

Here's what I think you're looking for:
C#
public delegate void CounterChangedHandler(object source, CounterChangedEventArgs e); 

public interface ICounterProcessor
{
  CounterChangedHandler CounterChanged { get; }
}

When you have pre-defined delegates like this, you can use them in the same way that you would Action or Func.
