When you go crazy (like me) because it doesn't work this time. Check the order of the calls. The OnPropertyChanged() must be called after the value was assigned.

public string Property1
{ 
    get { return _field1; } 
    set 
    {
        // assign the value first
        _field1 = value;

        // then call the property changed
        OnPropertyChanged("Property1");
    }
}
