???, take a look at this presentation from DevCon 2004:
http://www.intersystems.com/devcon2004/sessions/wednesday/InterSystems_and_NET.zip It's rather light on details but hopefully it will make sense to a .NET expert :) You may also want to search for previous posts via the archive at http://xiscsp.co.uk/ngp. In brief, I think there are no native components right now, you have to resort to OLEDB or ODBC (not much of a .NET developer myself :( ) A native component is promised for 5.1, due sometime this year.
