With entity framework, is it possible to add methods to an object class ? For example, i have a CLIENT mapping and i would like to create a "getAgeFromBirhDate" method.
Yes. It's possible. Entity Framework generates Partial Classes.
That means you can create another file that contains another portion of the Partial Class definition (with your additional methods) and everything will work just fine.
An example for first answer:
if you have an entity named Flower
you can use this partial
class for adding method to it:
namespace Garden //same as namespace of your entity object
{
public partial class Flower
{
public static Flower Get(int id)
{
//
}
}
}
