Hello Team,
I have added dll reference in my sharepoint web part application.

It doesn't have web.config so registered assembly using
<%@ Register Assembly="DropDownCheckBoxes" Namespace="Saplin.Controls" TagPrefix="asp" %>
on my aspx page. When i run it on browser, it giving us error as --

Could not load file or assembly 'DropDownCheckBoxes' or one of its dependencies. The system cannot find the file specified.


Can you please guide what needs to be done for this?
Thank You!
