Understanding MVVM Questions.

[TheUninvited]

#1 In the model we create our classes such as Person,Customer,
But what code goes inside there?

#2 In View is for the windows or the usercontrol we create such as Mainwindow.xaml with Mainwindow.cs Correct?
and that is the place we also do the bindings right?

#3 ViewModel is where the binding takes place i guess? such as if we had a FirstName it would load from here? or save data et.c
