c# application and dlls

Hi all, I developed an application exe that implements quite a few of dlls. Then I developed another program that uses the same dlls. In the release folders of each application, it shows those dlls. Since the dlls are the same, I am wondering if this is a good practice or not and whether or not this could work by having those dlls in one separate folder from each of my application. That way, both applications folders don't have to contain those same dlls?

how do I accomplish this? I might write more applications and potentially it would use the same dlls.

If you want to have one copy of a library used by multiple applications then that library needs to be installed in the Global Assembly Cache (GAC). That's exactly what happens with the libraries from the .NET Framework itself and various other common components that you may install along the way. Libraries can be installed in the GAC manually but it is usually done automatically by an installer. Look up the GAC on MSDN and you will find all the information you need.
