Quick question which I thought would be easily answered.
I have a .net website, which has references to dlls in the GAC.
When I build this and deploy to another server (in production) which doesn't have the same DLL references in the GAC, how can i get the dlls across?
If this is a manual process where you copy across you're website, you'll have to seperately copy your GAC dll and install that on your production server.
You can do this using GacUtil.exe (found in the Visual Studio/SDK/bin folder) or you can use the Admin Tools.NET Framework 2.0 Configuration MMC Snapin under Control Panel.
Have a look at this microsoft support article and this asp.net deployment options overview article.
