I have a big problem with MVVM design. I am trying to catch every PropertyChanged of my inner nested objects, including futhermore propertchanged of their nested objects, in

Answer 1

The best thing to do here is to separate the idea of a Model and a ViewModel.

By having a ViewModel object that is flatter than the Model you can avoid this scenario. Using an automatic mapping tool like Automapper then allows you to map the Model to the ViewModel and vice versa.

https://github.com/AutoMapper/AutoMapper/wiki/Flattening

class MyDatViewModel : INotifyPropertyChanged
{
    public string Str
    {
        // ... Get Set
    }

    public int NestedObjNum
    {
        // ... Get set
    }
}

// Configure AutoMapper

Mapper.CreateMap();

// Perform mapping

MyDatViewModel viewModel = Mapper.Map(someData);
