For instance, that all the entities override equals / get hash code. And yes, those are the naming convention I am talking about. http://ayende.com/3092/active-record-mapping-rewriting#comment3http://ayende.com/3092/active-record-mapping-rewriting#comment3Thu, 24 Jan 2008 04:19:59 GMTWhen you say we can apply naming conventions or validation do you mean that we could have classes declared public class MyClass { [Property] public string MyProperty { get; set; } } And apply a convention that column names all start with a type, so override the property declaration as if it were declared [Property("strMyProperty")] Also, what would be a use case for validations here?
