I know this topic has been discussed to death, but there is one thing that I can't wrap my head around.

I'm working on a Web Application using ASP.NET MVC and I come across a scenario where I need a helper class (this usually happens in the early stages of development. So I go ahead and create a helper project in my solution that I use to manage all of my Helper Classes.

Now, do I have to build that project and dump the dll in the bin directory every time I make changes to is, or is there a way to have the main web application reference the classes contained within the separate project without the separate build process?

I'm just looking for the easiest way to add helper classes without the hastel of building and moving the dll every time I make a change or addition.

Also, sorry for the very newbie-esque question here. All of the web apps I've build in the past have all been in the same project (web forms, App_Code, etc).
