We can still use a DLL with multiple applications - they're just shared between the different apps, and live with them. So if I have two apps Foo and Bar that both use PrettyTreeView.DLL, then I just put a copy of it in both projects, and save it in the same repository. Means I can keep the functionality nicely carved off in one place, but I don't have to worry about updating one app and breaking the other. Also, the DLL is only loaded in as needed - which saves on memory.
