I am starting a project with following technical environment : .Net 4.0, Entity Framework 4.0, WPF with MVVM Architecture
I saw lots of examples on the net, some books with this environment. In some of the examples authors had this Idea :
- Viemodel will have an instance of Model class (Entity Framework Entity e.g. Person)
- Bind the WPF view controls to the properties of Model
While some authors did :
- Viemodel will expose all the properties of the model.
- Bind the WPF view controls to the properties of ViewModel rather than to the model directly.
So is it a good idea to let the view bind properties from model rather than viewmodel exposing its own? Or which is more preferred?
