From the project side, this has included the addition of the IMvxInpcInterceptor - see http://slodge.blogspot.co.uk/2013/06/intercepting-raisepropertychanged.html
From the community, one of the most interesting projects I've seen is https://github.com/zleao/MvvmCross-PropertyChangedEventPropagation
- provides automated hooks to raise dependent property change notifications (so that FullName gets triggered whenever FirstName or LastName change)
- provides attributes for callback methods within ViewModels so that the ViewModel can execute code when
- extends all of this to child collections as well as to 'normal' properties
- comes with a full set of samples and a full readme too
This really is an awesome set of ideas - and to see it coded and shared as open source is superb.
Mvvm within C# is already a great tool for app development, but there's a lot of room for all of to grow, to learn and to evolve - and projects like PropertyChangedEventPropagation are most definitely part of the future.
zleao - awesome - big badge of awesomeness very happily awarded!
