Is the class internal?

I'll put a repo together asap.

I was referring to the second setup.

class A : ActiveRecorBase<A> {}

That one works as well:

>>> C.ancestors
=> [C, D[C], D[T], Object, Kernel]

I haven't tried it out, but perhaps Kevin was referring to this:
public class D<T> {
}
public class C : D<C> {
}

as opposed to what you tried:
public class D<T> {
}

public class E {
}

public class C : D<E> {
}

The distinction being that the subclasses type also happens to be the superclass's type arg.

Sorry for being too lazy to try it out... maybe later :)

Can you send a small repro of what doesn't work (both C# and Ruby code)?
It works for me.

test.cs:
public class D<T> {
}

public class E {
}

public class C : D<E> {
}

---
>>> require 'test.dll'
=> true
>>> C.new
=> C

Hello,

I have a few classes in a namespace that follow this form.

public class ExampleName : BaseClass<ExampleName>
{
}

Any class that follows this structure does not get pulled through when I require my DLL.

Does anyone have any ideas?

I'm also using the Castle ActiveRecord project and the classes that inherit from ActiveRecordBase<> also do not come through.

Thank you.
Kevin.
