Change Notification in MVVM Hierarchies

Question

Let\'s say in some abstract ViewModel base-class I have a plain-old property as follows:

public Size Size
{
    get { return _size; }
    set
    {
        _size         


        

Answer 1

I recently blogged about this exact problem. I include a [DependsUpon("Size")] attribute with the Rectangle. I REALLY like this approach, because it keeps the dependency knowledge with the code that creates the dependency, not the other way around.
