How do you get a different version from GAC
<p>Suppose I have released an application that uses an assembly that is in the GAC.</p>

<p>At a later date, I have a new version of the assembly. Do I remove the original version and install the new one or do I install the new one and make sure the application references it (via version numbers??).</p>

<p>What if I want older versions of the app to use the version they were installed with, whilst the new version of the application should use the new assembly?</p>
