Well, here are two extremes. Others hopefully will chime in with a middle
1. ArcGIS - Expensive ($2500) but very powerfull. You can either build
extensions to their product in VB (6 or .Net) or C#, or you can build an app
based on their objects. Your customer then must by the product. Big gotch:
their upgrades often break functionality, even going from 9.1 to 9.2 broke
2. Google Earth - Cheap (Free) but fairly functional mapping and the api
lets you launch and zoom to features. KML is a well documented xml format.
It really depends on how much GIS versus just mapping you need.
> Does anyone know of a good GIS plugin for VS 2005?
You might use MapPoint (desktop, stand alone -- or webservice), Visual
Earth, Google Earth, Tatsugis, and others.
