I have created an class library (1) that uses a CUSTOM DLL (2) and it is referenced in it properly.

This class library has been built for a "classic asp" legacy website.

I'll register application dll (1) and CUSTOM DLL (2) on the server.

When i'll create an object to my application dll (1), and use a method that utilizes CUSTOM DLL (2), will i get into an error or will the object get created and utilized?

If not, then how can i check in my application to see if "using CUSTOM DLL" has infact loaded the dll or not? And also, if not loaded then, how should i load it? I am planning on using this same in one of my MVC websites also where both will get referenced and then utilized without any problem.
