COM interop + inheritance

I have a method in COM object that returns inherited class B:
class A
{
void method1(int p1);
}

class B : A
{
void method2(int p2);
}

Tlbimp flatens classes, so from returned class B i can`t call
method1(). I tried casting returned class to class A, but when I try
to call method1(), I get "System.Runtime.InteropServices.COMException
(0x80020003): Member not found." exception.

Is there any way to handle this?
