DLL file is enough. Add it as a Reference to the project.

In your toolbox, right click the general tab and select 'Choose items'
You will be able to browse the DLL you want to. Browse it, select and press ok. Now, you will be able to see that DLL control in your toolbox.
Only if the DLL's project is in solution, by default VS add it to the toolbox.
