Using DependencyProperty in ViewModel with Entity Framework

I am writing a C # desktop application using the MVVM template with Entity Framework model. I tend to use DependencyProperties in my virtual machine and have come (usually), preferring this system over the implementation of INotifyPropertyChanged. I would like everything to be in order. My virtual machine accesses objects in the model, and I managed to save something quite separate - the view has no knowledge about VM, except for the name of bindings and commands, and the model knows information about the virtual machine.

Using INotifyPropertyChanged in a virtual machine, it seems pretty easy to update objects in a model:

public string Forename
    {
        get { return CurrentPerson.Forename; }
        set
        {
            if (Forename != value)
            {
                CurrentPerson.Forename = value;
                NotifyPropertyChanged("Forename");
            }
        }
    }

... CurrentPerson - Person, . , .
