Deploying SmartPart and the GAC vs Bin folder

Sep 3, 2008 at 5:38 PM
I am still getting my mind wrapped around MOSS and deploying webparts. In the video tutorial I see the part of the wizard where it deploys to the selected MOSS sites in the server farm. When it does that is it registering the SmartPart webpart in the GAC or is it copying the webpart to the bin folders for each of those sites? I just wonder how you would do upgrades if it's the latter. It seems the GAC way would be more beneficial.
