Created Unassigned: Recompile old version: namespaces not found ?? [7279]

Hello !

I am coming from version 4 .... and recompile a Tableviewer. Not a problem to use Messenger.GetTable instead of Manager, but wether "Variable", "SnmpException" nor "ObjectIdentifier" are recognized: "are you missing a reference ..".
I just have downloaded the latest 8.5... via NuGet, but the docs (chm) on Codeplex looks async to it ?? !! I dont have Visual Studio.

Any help would be great!

Thanks anyway and
best regards,

Manfred
