Validating Data Defined in Conceptual Models

When you use a conceptual model, you can define what kind of data is valid in the language that matches your domain. You can define valid data in the model, or you can add validation to operations that you perform on an entity or data service.

The following topics show how to add validation to Entity Framework and WCF Data Services applications.
