best practices for tier development in Visual Studio

Question

I have 3 projects

• website ( website )

• BusinessLogic ( Class Lib)

• UserControls (web application) // needs to be external

1) In order to debug the UserControls from website. Is it true all i need to is add a project reference from website to UserControls. This was working, but stop not sure why. Or shall i use a build event and copy the dll into the bin

2) If BusinessLogic require "thirdparty.dll" which currently lives in Website/bin. Is it best practise to add reference from Business Logic to "Website/bin/thirdparty.dl" or shall i just copy it into BusinessLogic project

Answer 1

I like to follow the clear dependence way.

If business logic depends on a third party library, put it there.

You website depends only on business logic, leave it as such.
