using c# .net dll in c# application

I have created a set of classes in a C# .Net Class Library application.
Now I want to use that set of classes in another C# .Net application.

I have added a reference to the .DLL and can see it in the reference list of the new project, however it is not "visible" (in intellisense) when I try "Using..." it.
I'm obviously missing something here and would greatly appreciate any help.

Thanks, James

Accepted answer
Have you remembered to declare your classes to be 'public' ?

If you don't do this, then they won't be accessible from outside the dll.

Hi Vulpes,
Great to get such a quick response.
And thank you, you were quite right, I hadn't declared the classes as public.
I thought that I might be able to still add it in a using clause, but I can see why that wouldn't be true.
However, as a relative new fellow, I think it would have been nice to get an indication when I added the reference. After all, what's the point of adding the reference if there is nothing accessible. :)
So thanks so much for your help ... much appreciated.
James
