Hello,

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

public class ExampleName : BaseClass  
{  
}

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.

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 {  
}

public class E {  
}

public class C : D {  
}

I haven’t tried it out, but perhaps Kevin was referring to this:

public class D {

}

public class C : D {

}

as opposed to what you tried:

public class D {

}

public class E {

}

public class C : D {

}

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 🙂

I’ll put a repo together asap.

I was referring to the second setup.

class A : ActiveRecorBase {}

That one works as well:

Is the class internal?
