Confirmed with Mike Fitzmaurice at Microsoft that SPS 2003 should work with NET 2.0 on the same box, and that SPS can index information stored in NET 2.0 web parts. Here is how:
- the IIS application running SPS must use NET 1.1 (ASP.NET tab)
- WSS SP2 is set up on a separate IIS application (virtual server) on the same machine, and configured to run NET 2.0
- Son of Smartpart is set up, and uses the WSS site
- Build webparts and controls in VS2005, and publish to WSS site
SPS should then be able to link to, and index the WSS site.
