top menu in msvs: Project-->Add Reference
3 tabs (?) : .net | com | browse
maybe you'll find it in the first 2, if not try browse -- I think it automatically copies the dll into the build folder.
To use it (and vb does it own unique thing when it comes importing namespaces for you?) you can try
Code:
Imports ProductNamespace
''Imports must at top of class declaration
or
Dim myObject As ProductNamespace.SeeIntellisense
maybe?
Not sure about toolbox items.
edit: Right click on a clear area in the toolbox and "Choose Items"
a few tabs: check .net and com probably.
