Where is the MOQ documentation?

Where can I find comprehensive documentation for MOQ? I'm just starting with mocking and am having difficulty getting my head around it. I've read through all the links at http://code.google.com/p/moq/wiki/QuickStart but can't seem to find a tutorial or gentle introduction.

I have also looked briefly at Rhino Mocks but found it very confusing.

Yes - I read Stephen Walthers article - very helpful. I also went through the links. I can't seem to watch the video at http://www.bestechvideos.com/2008/06/08/dimecasts-net-introduction-to-mocking-with-moq ^{[broken link]}

Specifically I am trying to determine whether an event was raised from the mocked class. I can't get the example for events on the QuickStarts page to compile. On the google groups, Daniel explained that CreateEventHandler can only handle an event of type EventHandler<TEventArgs>, but even then I can't get the code to compile.

More specifically I have a class that implements INotifyChanged.

public class Entity : INotifyChanged
{
    public event PropertyChangingEventHandler PropertyChanging;

    public int Id 
      { 
          get {return _id;}
          set {
                 _id = value;
                 OnPropertyChanged("Id");
              }
      }

     protected void OnPropertyChanged(string property)
      {
         if (PropertyChanged != null)
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
      }
 etc .....    
}

How do I mock the class to test whether the PropertyChanged event was fired? I can't rewrite the event to public event EventHandler<PropertyChangedEventArgs> becuase I get this error:

Error 1 'CoreServices.Notifier' does not implement interface member System.ComponentModel.INotifyPropertyChanged.PropertyChanged'. 'CoreServices.Notifier.PropertyChanged' cannot implement 'System.ComponentModel.INotifyPropertyChanged.PropertyChanged' because it does not have the matching return type of 'System.ComponentModel.PropertyChangedEventHandler'.
