I am trying to understand how to update the UI if I have a read-only property that is dependent on another property, so that changes to one property update both UI elements

You could simply call

OnPropertyChanged(this, "bar");

from anywhere in this class...You cold even go like this:

    public raz()
    {
        this.PropertyChanged += new PropertyChangedEventHandler(raz_PropertyChanged);
    }

    void raz_PropertyChanged(object sender, PropertyChangedEventArgs e)
    {
        if(e.PropertyName == "foo")
        {
             onPropertyChanged(this, "bar");
        }
    }
