           Summary: ReflectionPropertyDescriptor.AddValueChanged doesn't
                    use object property xxxChanged events
    Classification: Mono
           Product: Mono: Class Libraries
           Version: 2.6.x

TypeDescriptor.GetProperties(typeof(Entity))["Property"].AddValueChanged(entity,
Entity_PropertyChanged);
should hook the PropertyChanged event below, as ms.net does.

public class Entity
{
    public string Property
    {
        get { return mProperty; }
        set
        {
            mProperty = value;
            PropertyChanged.Raise(this, EventArgs.Empty);
        }
    }

    public event EventHandler PropertyChanged;
}


Reproducible: Always

Steps to Reproduce:
1. Create an entity class like the one above
2. Hook the changed event via the PropertyDescriptor:
TypeDescriptor.GetProperties(typeof(Entity))["Property"].AddValueChanged(entity,
Entity_PropertyChanged);
3. Changed the value of Property via the object itself (not the
PropertyDescriptor.SetValue method)

Actual Results:  
The event handler is not invoked

Expected Results:  
The event handler should be invoked
