2017.2 OSX - "Loading script assembly "Assets/Plugins/I18N.dll" failed!"

Question

Running 2017.2, have it hooked up to Visual Studio for Mac.

When I try to add a folder for plugins and add some DLLs for things like i18n (on one project need to access encodings like 1252 for certain text I/O), System.Data (Mono.Data) for SQL/SQLite, System.Security (System.ComponentModel.Component.WebClient won't work without Security loaded), etc I get Loading script assembly errors like the above.

Where do I need to go to copy the right DLLs on Mac?

Answer 1

Found some that look like they work (at least they import without errors) at: /Applications/Unity/Unity.app/Contents/MonoBleedingEdge/lib/mono/unity/

but whenever I use WebClient I get this:
