Validation of WPF User Input using MVVM and Entity Framework 4.0

Question

I am building a WPF 4.0 Application using MVVM. The Model is generated using Entity Framework 4.0. I am using Data binding on the WPF to bind the user input to model properties.

What is the easiest way to validate user input ? I prefer an approach where I can set the validation rules on the Model rather than on the WPF itself. How can this be done? Any samples are appreciated.

Please take a look at http://stackoverflow.com/questions/1755340/validate-data-using-dataannotations-with-wpf-entity-framework.

Answer 2

The BookLibrary sample application of the WPF Application Framework (WAF) project shows a MVVM application. It uses the Entity Framework and defines the validation rules on the Model (Entity) classes.
