title: dll reference - GAC vs Bin
body: <blockquote>
    <p>I have two project in my visual studio solution project A and project
    B. Project A deploys its dll into the GAC.  Project B references the
    dll of project A. Now I would like to know whether I should add the
    reference of project A from its' bin directory or from GAC, which one
    is the good practice.</p>
