Package dependent dll's

Question

Hi, I am working on a control which uses one my own previously written classes (let's call it ClassA). I add a reference to the class and add a using statement in the code of my control. Everything works fine when testing the control, just as it should. My problem is that when I use this control in another project (either by adding a reference and a using statement or via the toolbox) the compiler complains that it cannot find ClassA. Is there a way to avoid having to reference ClassA everytime I want to use my control, maybe packing the ClassA dll within the control assembly? TIA Matt.
