Hey folks,

I've flagged an entity as abstract in the designer but it's not being marked as abstract in the generated code. Using latest 2.0 build... (adapter/.net 2.0)

I get: public partial class PolicyEntity : EntityBase2, ISerializable, IPolicy

(The IPolicy is an extra interface that put's in via the designer)

As you can see there's no abstract keyword in the class definition.

I've attached my project file.

By design, abstract entities need to be instantiated by the internal engine for example when fetching all the entities of that type (and subtypes). The ctor is internal though.

So... what does that mean? It's not supposed to put the abstract keyword in the class definition? What's the point of it then?

A class containing an internal constructor cannot be instantiated outside of the assembly. An internal constructor can be used to limit concrete implementations of the abstract class to the assembly defining the class.

So from your application you can not instantiate from that entity class.

The runtime needs to create a dummy instance of an entity to determine the fields. If you fetch for example 'employees' where employee is an abstract entity, it has to produce an entity instance. that's why the ctor is internal so the factory can instantiate one, the rest can't.
