Seems to be a recurring nightmare here, but it seems ESRI UK gave us a bum steer. You do not need to install ArcObjects .NET SDK (and, of course, the obligatory VS IDE), but you do need to have an installation of one of the desktop products in order to be able to use the dlls.
Heres a link to the help page, but it appears you need to have ArcMap/ArcCatalog/etc installed in order to fully be able to deploy any application you've developed using ArcObjects? Is this insanity on my part?
I would have thought the easiest way would be to bundle the dlls, but am told you can reference the GAC dlls (Not too sure I understand this so a steer would be appreciated). However, ESRI docs seem to clearly state they cannot be deployed without an appropriate ArcGIS Desktop application installed.
Surely this is just for custom Desktop tools and not AGS tools?
