I was trying to place a UserControl inside the App_Code
folder. The main reason for putting the UserControl inside App_Code folder was
to make it as a BaseUserControl so that other UserControls are able to inherit
from it. Whenever I tried to add a UserControl in the folder it throws the
exception saying that UserControls are not permitted in the App_Code folder.
This is little strange since I have a webform which is also inside the App_Code
folder. The webform (Page) serves as the BasePage for other ASP.NET pages.
